+#########################################################################
+# The boost threading library can be built on top of different API's
+# Currently this is the win32 API and the pthreads API.
+# Pthread is native on unix variants.
+# To get pthread on windows you need the pthread win32 library
+# http://sourceware.org/pthreads-win32 which is available under LGPL.
+#
+# You need to provide the include path and lib path in the variables
+# PTW32_INCLUDE and PTW32_LIB respectively. You can specify these
+# paths in site-config.jam, user-config.jam or in the environment.
+# A new feature is provided to request a specific API:
+# <threadapi>win32 and <threadapi)pthread.
+#
+# The naming of the resulting libraries is mostly the same for the
+# variant native to the build platform, i.e.
+# boost_thread and the boost specific tagging.
+# For the library variant that is not native on the build platform
+# an additional tag is applied:
+# boost_thread_pthread for the pthread variant on windows, and
+# boost_thread_win32 for the win32 variant (likely when built on cygwin).
+#
+# To request the pthread variant on windows, from boost root you would
+# say e.g:
+# bjam msvc-8.0 --with-thread install threadapi=pthread

+[section:acknowledgements Acknowledgments]
+
+The original implementation of __boost_thread__ was written by William Kempf, with contributions from numerous others. This new
+version initially grew out of an attempt to rewrite __boost_thread__ to William Kempf's design with fresh code that could be
+released under the Boost Software License. However, as the C++ Standards committee have been actively discussing standardizing a
+thread library for C++, this library has evolved to reflect the proposals, whilst retaining as much backwards-compatibility as
+possible.
+
+Particular thanks must be given to Roland Schwarz, who contributed a lot of time and code to the original __boost_thread__ library,
+and who has been actively involved with the rewrite. The scheme for dividing the platform-specific implementations into separate
+directories was devised by Roland, and his input has contributed greatly to improving the quality of the current implementation.
+
+Thanks also must go to Peter Dimov, Howard Hinnant, Alexander Terekhov, Chris Thomasson and others for their comments on the
+implementation details of the code.

+[section:barriers Barriers]
+
+A barrier is a simple concept. Also known as a ['rendezvous], it is a synchronization point between multiple threads. The barrier is
+configured for a particular number of threads (`n`), and as threads reach the barrier they must wait until all `n` threads have
+arrived. Once the `n`-th thread has reached the barrier, all the waiting threads can proceed, and the barrier is reset.
+
+[section:barrier Class `barrier`]
+
+ #include <boost/thread/barrier.hpp>
+
+ class barrier
+ {
+ public:
+ barrier(unsigned int count);
+ ~barrier();
+
+ bool wait();

+
+Instances of __barrier__ are not copyable or movable.

+[section:changes Changes since boost 1.35]
+
+The 1.36.0 release of Boost includes a few new features in the thread library:
+
+* New generic __lock_multiple_ref__ and __try_lock_multiple_ref__ functions for locking multiple mutexes at once.
+
+* Rvalue reference support for move semantics where the compilers supports it.
+
+* A few bugs fixed and missing functions added (including the serious win32 condition variable bug).
+
+* `scoped_try_lock` types are now backwards-compatible with Boost 1.34.0 and previous releases.
+
+* Support for passing function arguments to the thread function by supplying additional arguments to the __thread__ constructor.
+
+* Backwards-compatibility overloads added for `timed_lock` and `timed_wait` functions to allow use of `xtime` for timeouts.
+
+[heading Changes since boost 1.34]
+
+Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface
+changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking
+changes are described below.
+
+[heading New Features]
+
+* Instances of __thread__ and of the various lock types are now movable.
+
+* Threads can be interrupted at __interruption_points__.
+
+* Condition variables can now be used with any type that implements the __lockable_concept__, through the use of
+`boost::condition_variable_any` (`boost::condition` is a `typedef` to `boost::condition_variable_any`, provided for backwards
+compatibility). `boost::condition_variable` is provided as an optimization, and will only work with
+`boost::unique_lock<boost::mutex>` (`boost::mutex::scoped_lock`).
+
+* Thread IDs are separated from __thread__, so a thread can obtain it's own ID (using `boost::this_thread::get_id()`), and IDs can
+be used as keys in associative containers, as they have the full set of comparison operators.
+
+* Timeouts are now implemented using the Boost DateTime library, through a typedef `boost::system_time` for absolute timeouts, and
+with support for relative timeouts in many cases. `boost::xtime` is supported for backwards compatibility only.
+
+* Locks are implemented as publicly accessible templates `boost::lock_guard`, `boost::unique_lock`, `boost::shared_lock`, and
+`boost::upgrade_lock`, which are templated on the type of the mutex. The __lockable_concept__ has been extended to include publicly
+available __lock_ref__ and __unlock_ref__ member functions, which are used by the lock types.
+
+[heading Breaking Changes]
+
+The list below should cover all changes to the public interface which break backwards compatibility.
+
+* __try_mutex__ has been removed, and the functionality subsumed into __mutex__. __try_mutex__ is left as a `typedef`,
+but is no longer a separate class.
+
+* __recursive_try_mutex__ has been removed, and the functionality subsumed into
+__recursive_mutex__. __recursive_try_mutex__ is left as a `typedef`, but is no longer a separate class.
+
+* `boost::detail::thread::lock_ops` has been removed. Code that relies on the `lock_ops` implementation detail will no longer work,
+as this has been removed, as it is no longer necessary now that mutex types now have public __lock_ref__ and __unlock_ref__ member
+functions.
+
+* `scoped_lock` constructors with a second parameter of type `bool` are no longer provided. With previous boost releases,
+``boost::mutex::scoped_lock some_lock(some_mutex,false);`` could be used to create a lock object that was associated with a mutex,
+but did not lock it on construction. This facility has now been replaced with the constructor that takes a
+`boost::defer_lock_type` as the second parameter: ``boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);``
+
+* The `locked()` member function of the `scoped_lock` types has been renamed to __owns_lock_ref__.
+
+* You can no longer obtain a __thread__ instance representing the current thread: a default-constructed __thread__ object is not
+associated with any thread. The only use for such a thread object was to support the comparison operators: this functionality has
+been moved to __thread_id__.
+
+* The broken `boost::read_write_mutex` has been replaced with __shared_mutex__.
+
+* __mutex__ is now never recursive. For Boost releases prior to 1.35 __mutex__ was recursive on Windows and not on POSIX platforms.
+
+* When using a __recursive_mutex__ with a call to [cond_any_wait_link `boost::condition_variable_any::wait()`], the mutex is only
+ unlocked one level, and not completely. This prior behaviour was not guaranteed and did not feature in the tests.

+[section:condvar_ref Condition Variables]
+
+[heading Synopsis]
+
+The classes `condition_variable` and `condition_variable_any` provide a
+mechanism for one thread to wait for notification from another thread that a
+particular condition has become true. The general usage pattern is that one
+thread locks a mutex and then calls `wait` on an instance of
+`condition_variable` or `condition_variable_any`. When the thread is woken from
+the wait, then it checks to see if the appropriate condition is now true, and
+continues if so. If the condition is not true, then the thread then calls `wait`
+again to resume waiting. In the simplest case, this condition is just a boolean
+variable:
+
+ boost::condition_variable cond;
+ boost::mutex mut;
+ bool data_ready;
+
+ void process_data();
+
+ void wait_for_data_to_process()
+ {
+ boost::unique_lock<boost::mutex> lock(mut);
+ while(!data_ready)
+ {
+ cond.wait(lock);
+ }
+ process_data();
+ }
+
+Notice that the `lock` is passed to `wait`: `wait` will atomically add the
+thread to the set of threads waiting on the condition variable, and unlock the
+mutex. When the thread is woken, the mutex will be locked again before the call
+to `wait` returns. This allows other threads to acquire the mutex in order to
+update the shared data, and ensures that the data associated with the condition
+is correctly synchronized.
+
+In the mean time, another thread sets the condition to `true`, and then calls
+either `notify_one` or `notify_all` on the condition variable to wake one
+waiting thread or all the waiting threads respectively.
+
+ void retrieve_data();
+ void prepare_data();
+
+ void prepare_data_for_processing()
+ {
+ retrieve_data();
+ prepare_data();
+ {
+ boost::lock_guard<boost::mutex> lock(mut);
+ data_ready=true;
+ }
+ cond.notify_one();
+ }
+
+Note that the same mutex is locked before the shared data is updated, but that
+the mutex does not have to be locked across the call to `notify_one`.
+
+This example uses an object of type `condition_variable`, but would work just as
+well with an object of type `condition_variable_any`: `condition_variable_any`
+is more general, and will work with any kind of lock or mutex, whereas
+`condition_variable` requires that the lock passed to `wait` is an instance of
+`boost::unique_lock<boost::mutex>`. This enables `condition_variable` to make
+optimizations in some cases, based on the knowledge of the mutex type;
+`condition_variable_any` typically has a more complex implementation than
+`condition_variable`.

+[section:mutex_concepts Mutex Concepts]
+
+A mutex object facilitates protection against data races and allows thread-safe synchronization of data between threads. A thread
+obtains ownership of a mutex object by calling one of the lock functions and relinquishes ownership by calling the corresponding
+unlock function. Mutexes may be either recursive or non-recursive, and may grant simultaneous ownership to one or many
+threads. __boost_thread__ supplies recursive and non-recursive mutexes with exclusive ownership semantics, along with a shared
+ownership (multiple-reader / single-writer) mutex.
+
+__boost_thread__ supports four basic concepts for lockable objects: __lockable_concept_type__, __timed_lockable_concept_type__,
+__shared_lockable_concept_type__ and __upgrade_lockable_concept_type__. Each mutex type implements one or more of these concepts, as
+do the various lock types.
+
+[section:lockable `Lockable` Concept]
+
+The __lockable_concept__ models exclusive ownership. A type that implements the __lockable_concept__ shall provide the following
+member functions:
+
+* [lock_ref_link `void lock();`]
+* [try_lock_ref_link `bool try_lock();`]
+* [unlock_ref_link `void unlock();`]
+
+Lock ownership acquired through a call to __lock_ref__ or __try_lock_ref__ must be released through a call to __unlock_ref__.

+
+The __shared_lockable_concept__ is a refinement of the __timed_lockable_concept__ that
+allows for ['shared ownership] as well as ['exclusive ownership]. This is the
+standard multiple-reader / single-write model: at most one thread can have
+exclusive ownership, and if any thread does have exclusive ownership, no other threads
+can have shared or exclusive ownership. Alternatively, many threads may have
+shared ownership.
+
+For a type to implement the __shared_lockable_concept__, as well as meeting the
+requirements of the __timed_lockable_concept__, it must also provide the following
+member functions:
+
+* [lock_shared_ref_link `void lock_shared();`]
+* [try_lock_shared_ref_link `bool try_lock_shared();`]
+* [unlock_shared_ref_link `bool unlock_shared();`]
+* [timed_lock_shared_ref_link `bool timed_lock_shared(boost::system_time const& abs_time);`]
+
+Lock ownership acquired through a call to __lock_shared_ref__, __try_lock_shared_ref__ or __timed_lock_shared_ref__ must be released
+through a call to __unlock_shared_ref__.

+
+The __upgrade_lockable_concept__ is a refinement of the __shared_lockable_concept__ that allows for ['upgradable ownership] as well
+as ['shared ownership] and ['exclusive ownership]. This is an extension to the multiple-reader / single-write model provided by the
+__shared_lockable_concept__: a single thread may have ['upgradable ownership] at the same time as others have ['shared
+ownership]. The thread with ['upgradable ownership] may at any time attempt to upgrade that ownership to ['exclusive ownership]. If
+no other threads have shared ownership, the upgrade is completed immediately, and the thread now has ['exclusive ownership], which
+must be relinquished by a call to __unlock_ref__, just as if it had been acquired by a call to __lock_ref__.
+
+If a thread with ['upgradable ownership] tries to upgrade whilst other threads have ['shared ownership], the attempt will fail and
+the thread will block until ['exclusive ownership] can be acquired.
+
+Ownership can also be ['downgraded] as well as ['upgraded]: exclusive ownership of an implementation of the
+__upgrade_lockable_concept__ can be downgraded to upgradable ownership or shared ownership, and upgradable ownership can be
+downgraded to plain shared ownership.
+
+For a type to implement the __upgrade_lockable_concept__, as well as meeting the
+requirements of the __shared_lockable_concept__, it must also provide the following
+member functions:
+
+* [lock_upgrade_ref_link `void lock_upgrade();`]
+* [unlock_upgrade_ref_link `bool unlock_upgrade();`]
+* [unlock_upgrade_and_lock_ref_link `void unlock_upgrade_and_lock();`]

+* [unlock_upgrade_and_lock_shared_ref_link `void unlock_upgrade_and_lock_shared();`]
+
+Lock ownership acquired through a call to __lock_upgrade_ref__ must be released through a call to __unlock_upgrade_ref__. If the
+ownership type is changed through a call to one of the `unlock_xxx_and_lock_yyy()` functions, ownership must be released through a
+call to the unlock function corresponding to the new level of ownership.

+__lock_guard__ is very simple: on construction it

+
+__unique_lock__ is more complex than __lock_guard__: not only does it provide for RAII-style locking, it also allows for deferring
+acquiring the lock until the __lock_ref__ member function is called explicitly, or trying to acquire the lock in a non-blocking
+fashion, or with a timeout. Consequently, __unlock_ref__ is only called in the destructor if the lock object has locked the
+__lockable_concept_type__ object, or otherwise adopted a lock on the __lockable_concept_type__ object.
+
+Specializations of __unique_lock__ model the __timed_lockable_concept__ if the supplied __lockable_concept_type__ type itself models
+__timed_lockable_concept__ (e.g. `boost::unique_lock<boost::timed_mutex>`), or the __lockable_concept__ otherwise
+(e.g. `boost::unique_lock<boost::mutex>`).
+
+An instance of __unique_lock__ is said to ['own] the lock state of a __lockable_concept_type__ `m` if __mutex_func_ref__ returns a
+pointer to `m` and __owns_lock_ref__ returns `true`. If an object that ['owns] the lock state of a __lockable_concept_type__ object
+is destroyed, then the destructor will invoke [unlock_ref_link `mutex()->unlock()`].
+
+The member functions of __unique_lock__ are not thread-safe. In particular, __unique_lock__ is intended to model the ownership of a
+__lockable_concept_type__ object by a particular thread, and the member functions that release ownership of the lock state
+(including the destructor) must be called by the same thread that acquired ownership of the lock state.

+
+Like __unique_lock__, __upgrade_lock__ models the __lockable_concept__, but rather than acquiring unique ownership of the supplied
+__lockable_concept_type__ object, locking an instance of __upgrade_lock__ acquires upgrade ownership.
+
+Like __unique_lock__, not only does it provide for RAII-style locking, it also allows for deferring acquiring the lock until the
+__lock_ref__ member function is called explicitly, or trying to acquire the lock in a non-blocking fashion, or with a
+timeout. Consequently, __unlock_ref__ is only called in the destructor if the lock object has locked the __lockable_concept_type__
+object, or otherwise adopted a lock on the __lockable_concept_type__ object.
+
+An instance of __upgrade_lock__ is said to ['own] the lock state of a __lockable_concept_type__ `m` if __mutex_func_ref__ returns a
+pointer to `m` and __owns_lock_ref__ returns `true`. If an object that ['owns] the lock state of a __lockable_concept_type__ object
+is destroyed, then the destructor will invoke [unlock_upgrade_ref_link `mutex()->unlock_upgrade()`].
+
+The member functions of __upgrade_lock__ are not thread-safe. In particular, __upgrade_lock__ is intended to model the upgrade
+ownership of a __lockable_concept_type__ object by a particular thread, and the member functions that release ownership of the lock
+state (including the destructor) must be called by the same thread that acquired ownership of the lock state.

+
+__upgrade_to_unique_lock__ allows for a temporary upgrade of an __upgrade_lock__ to exclusive ownership. When constructed with a
+reference to an instance of __upgrade_lock__, if that instance has upgrade ownership on some __lockable_concept_type__ object, that
+ownership is upgraded to exclusive ownership. When the __upgrade_to_unique_lock__ instance is destroyed, the ownership of the
+__lockable_concept_type__ is downgraded back to ['upgrade ownership].

+
+__boost_thread__ enables the use of multiple threads of execution with shared data in portable C++ code. It provides classes and
+functions for managing the threads themselves, along with others for synchronizing data between the threads or providing separate
+copies of data specific to individual threads.
+
+The __boost_thread__ library was originally written and designed by William E. Kempf. This version is a major rewrite designed to
+closely follow the proposals presented to the C++ Standards Committee, in particular
+[@http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2497.html N2497],

+[section:thread_management Thread Management]
+
+[heading Synopsis]
+
+The __thread__ class is responsible for launching and managing threads. Each __thread__ object represents a single thread of execution,
+or __not_a_thread__, and at most one __thread__ object represents a given thread of execution: objects of type __thread__ are not
+copyable.
+
+Objects of type __thread__ are movable, however, so they can be stored in move-aware containers, and returned from functions. This
+allows the details of thread creation to be wrapped in a function.
+
+ boost::thread make_thread();
+
+ void f()
+ {
+ boost::thread some_thread=make_thread();
+ some_thread.join();
+ }
+
+[Note: On compilers that support rvalue references, __thread__ provides a proper move constructor and move-assignment operator, and
+therefore meets the C++0x ['MoveConstructible] and ['MoveAssignable] concepts. With such compilers, __thread__ can therefore be used
+with containers that support those concepts.
+
+For other compilers, move support is provided with a move emulation layer, so containers must explicitly detect that move emulation
+layer. See <boost/thread/detail/move.hpp> for details.]
+
+[heading Launching threads]
+
+A new thread is launched by passing an object of a callable type that can be invoked with no parameters to the constructor. The
+object is then copied into internal storage, and invoked on the newly-created thread of execution. If the object must not (or
+cannot) be copied, then `boost::ref` can be used to pass in a reference to the function object. In this case, the user of
+__boost_thread__ must ensure that the referred-to object outlives the newly-created thread of execution.
+
+ struct callable
+ {
+ void operator()();
+ };
+
+ boost::thread copies_are_safe()
+ {
+ callable x;
+ return boost::thread(x);
+ } // x is destroyed, but the newly-created thread has a copy, so this is OK
+
+ boost::thread oops()
+ {
+ callable x;
+ return boost::thread(boost::ref(x));
+ } // x is destroyed, but the newly-created thread still has a reference
+ // this leads to undefined behaviour
+
+If you wish to construct an instance of __thread__ with a function or callable object that requires arguments to be supplied,
+this can be done by passing additional arguments to the __thread__ constructor:
+
+ void find_the_question(int the_answer);
+
+ boost::thread deep_thought_2(find_the_question,42);
+
+The arguments are ['copied] into the internal thread structure: if a reference is required, use `boost::ref`, just as for references
+to callable functions.
+
+There is an unspecified limit on the number of additional arguments that can be passed.
+
+[heading Exceptions in thread functions]
+
+If the function or callable object passed to the __thread__ constructor propagates an exception when invoked that is not of type
+__thread_interrupted__, `std::terminate()` is called.
+
+[heading Joining and detaching]
+
+When the __thread__ object that represents a thread of execution is destroyed the thread becomes ['detached]. Once a thread is
+detached, it will continue executing until the invocation of the function or callable object supplied on construction has completed,
+or the program is terminated. A thread can also be detached by explicitly invoking the __detach__ member function on the __thread__
+object. In this case, the __thread__ object ceases to represent the now-detached thread, and instead represents __not_a_thread__.
+
+In order to wait for a thread of execution to finish, the __join__ or __timed_join__ member functions of the __thread__ object must be
+used. __join__ will block the calling thread until the thread represented by the __thread__ object has completed. If the thread of
+execution represented by the __thread__ object has already completed, or the __thread__ object represents __not_a_thread__, then __join__
+returns immediately. __timed_join__ is similar, except that a call to __timed_join__ will also return if the thread being waited for
+does not complete when the specified time has elapsed.
+
+[heading Interruption]
+
+A running thread can be ['interrupted] by invoking the __interrupt__ member function of the corresponding __thread__ object. When the
+interrupted thread next executes one of the specified __interruption_points__ (or if it is currently __blocked__ whilst executing one)
+with interruption enabled, then a __thread_interrupted__ exception will be thrown in the interrupted thread. If not caught,
+this will cause the execution of the interrupted thread to terminate. As with any other exception, the stack will be unwound, and
+destructors for objects of automatic storage duration will be executed.
+
+If a thread wishes to avoid being interrupted, it can create an instance of __disable_interruption__. Objects of this class disable
+interruption for the thread that created them on construction, and restore the interruption state to whatever it was before on
+destruction:
+
+ void f()
+ {
+ // interruption enabled here
+ {
+ boost::this_thread::disable_interruption di;
+ // interruption disabled
+ {
+ boost::this_thread::disable_interruption di2;
+ // interruption still disabled
+ } // di2 destroyed, interruption state restored
+ // interruption still disabled
+ } // di destroyed, interruption state restored
+ // interruption now enabled
+ }
+
+The effects of an instance of __disable_interruption__ can be temporarily reversed by constructing an instance of
+__restore_interruption__, passing in the __disable_interruption__ object in question. This will
+restore the interruption state to what it was when the __disable_interruption__ object was constructed, and then
+disable interruption again when the __restore_interruption__ object is destroyed.
+
+ void g()
+ {
+ // interruption enabled here
+ {
+ boost::this_thread::disable_interruption di;
+ // interruption disabled
+ {
+ boost::this_thread::restore_interruption ri(di);
+ // interruption now enabled
+ } // ri destroyed, interruption disable again
+ } // di destroyed, interruption state restored
+ // interruption now enabled
+ }
+
+At any point, the interruption state for the current thread can be queried by calling __interruption_enabled__.
+
+[#interruption_points]
+
+[heading Predefined Interruption Points]
+
+The following functions are ['interruption points], which will throw __thread_interrupted__ if interruption is enabled for the
+current thread, and interruption is requested for the current thread:
+
+* [join_link `boost::thread::join()`]
+* [timed_join_link `boost::thread::timed_join()`]
+* [cond_wait_link `boost::condition_variable::wait()`]
+* [cond_timed_wait_link `boost::condition_variable::timed_wait()`]
+* [cond_any_wait_link `boost::condition_variable_any::wait()`]
+* [cond_any_timed_wait_link `boost::condition_variable_any::timed_wait()`]
+* [link thread.thread_management.thread.sleep `boost::thread::sleep()`]
+* __sleep__
+* __interruption_point__
+
+[heading Thread IDs]
+
+Objects of class __thread_id__ can be used to identify threads. Each running thread of execution has a unique ID obtainable
+from the corresponding __thread__ by calling the `get_id()` member function, or by calling `boost::this_thread::get_id()` from
+within the thread. Objects of class __thread_id__ can be copied, and used as keys in associative containers: the full range of
+comparison operators is provided. Thread IDs can also be written to an output stream using the stream insertion operator, though the
+output format is unspecified.
+
+Each instance of __thread_id__ either refers to some thread, or __not_a_thread__. Instances that refer to __not_a_thread__
+compare equal to each other, but not equal to any instances that refer to an actual thread of execution. The comparison operators on
+__thread_id__ yield a total order for every non-equal thread ID.

+[section:time Date and Time Requirements]
+
+As of Boost 1.35.0, the __boost_thread__ library uses the [link date_time Boost.Date_Time] library for all operations that require a
+time out. These include (but are not limited to):
+
+* __sleep__
+* __timed_join__
+* __cond_timed_wait__
+* __timed_lock_ref__
+
+For the overloads that accept an absolute time parameter, an object of type [link thread.time.system_time `boost::system_time`] is
+required. Typically, this will be obtained by adding a duration to the current time, obtained with a call to [link
+thread.time.get_system_time `boost::get_system_time()`]. e.g.
+
+ boost::system_time const timeout=boost::get_system_time() + boost::posix_time::milliseconds(500);
+
+ extern bool done;
+ extern boost::mutex m;
+ extern boost::condition_variable cond;
+
+ boost::unique_lock<boost::mutex> lk(m);
+ while(!done)
+ {
+ if(!cond.timed_wait(lk,timeout))
+ {
+ throw "timed out";
+ }
+ }
+
+For the overloads that accept a ['TimeDuration] parameter, an object of any type that meets the [link
+date_time.posix_time.time_duration Boost.Date_Time Time Duration requirements] can be used, e.g.
+
+ boost::this_thread::sleep(boost::posix_time::milliseconds(25));
+
+ boost::mutex m;
+ if(m.timed_lock(boost::posix_time::nanoseconds(100)))
+ {
+ // ...

+[section Thread Local Storage]
+
+[heading Synopsis]
+
+Thread local storage allows multi-threaded applications to have a separate instance of a given data item for each thread. Where a
+single-threaded application would use static or global data, this could lead to contention, deadlock or data corruption in a
+multi-threaded application. One example is the C `errno` variable, used for storing the error code related to functions from the
+Standard C library. It is common practice (and required by POSIX) for compilers that support multi-threaded applications to provide
+a separate instance of `errno` for each thread, in order to avoid different threads competing to read or update the value.
+
+Though compilers often provide this facility in the form of extensions to the declaration syntax (such as `__declspec(thread)` or
+`__thread` annotations on `static` or namespace-scope variable declarations), such support is non-portable, and is often limited in
+some way, such as only supporting POD types.
+
+[heading Portable thread-local storage with `boost::thread_specific_ptr`]
+
+`boost::thread_specific_ptr` provides a portable mechanism for thread-local storage that works on all compilers supported by
+__boost_thread__. Each instance of `boost::thread_specific_ptr` represents a pointer to an object (such as `errno`) where each
+thread must have a distinct value. The value for the current thread can be obtained using the `get()` member function, or by using
+the `*` and `->` pointer deference operators. Initially the pointer has a value of `NULL` in each thread, but the value for the
+current thread can be set using the `reset()` member function.
+
+If the value of the pointer for the current thread is changed using `reset()`, then the previous value is destroyed by calling the
+cleanup routine. Alternatively, the stored value can be reset to `NULL` and the prior value returned by calling the `release()`
+member function, allowing the application to take back responsibility for destroying the object.
+
+[heading Cleanup at thread exit]
+
+When a thread exits, the objects associated with each `boost::thread_specific_ptr` instance are destroyed. By default, the object
+pointed to by a pointer `p` is destroyed by invoking `delete p`, but this can be overridden for a specific instance of
+`boost::thread_specific_ptr` by providing a cleanup routine to the constructor. In this case, the object is destroyed by invoking
+`func(p)` where `func` is the cleanup routine supplied to the constructor. The cleanup functions are called in an unspecified
+order. If a cleanup routine sets the value of associated with an instance of `boost::thread_specific_ptr` that has already been
+cleaned up, that value is added to the cleanup list. Cleanup finishes when there are no outstanding instances of
+`boost::thread_specific_ptr` with values.

+ functions at the appropriate times (and for implementing an a
+ tss_cleanup_implemented() function to eliminate the linker's
+ missing symbol error).
+
+ If Boost.Threads later implements automatic tss cleanup in cases

+ symbol error will warn the user that their custom solution is no
