--- Comment #21 from Martin Nowak <code at dawg.eu> ---
Nope, that doesn't seem to be the problem.
All the thread exit code synchronizes on Thread.slock_nothrow.
It shouldn't even be possible to send a signal to an exiting thread, b/c they
get removed from the thread list before that, and that is synchronized around
the suspend loop.

Might still be a problem with the synchronization of m_isRunning and/or
thread_cleanupHandler. Did your apps by any chance use thread cancellation or
pthread_exit?
