On a 2-way box (2x i686) a cancelation handler sometimes fails to unlock the
mutex (errorcheck type) when the thread is canceled during
pthread_cond_timedwait operation.
The glibc is a CVS checkout from 2004-08-03, configured with NPTL support.
The compiler is gcc 3.4.1
The kernel is 2.6.7 #2 SMP Thu Jul 22 15:00:28 CEST 2004 i686 i686 i386 GNU/Linux
I can provide a sample to reproduce the problem (but it happens randomly :-( )
