        seems to be that the call disables long double computations which
        revert to just double precision. This then leads to an endless loop in
        computing weights for quadrature points because the convergence
        criterion cannot be reached with simple double precision. This is now
        fixed by disabling the call to <code>gethostname()</code> on these

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
