Subject: Remove DeadlockKiller from tests. The rationale is
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8612325a05147a5bbde7298ad3ddea126212afd8;p=dealii-svn.git

Remove DeadlockKiller from tests. The rationale is

 (a) it is no longer necessary with ctest which will take care of killing
     deadlocked tests, too.

 (b) exiting on the main thread without joining the other threads first
     violates current language standard - so a significant rewrite would be
     necessary
