We also had problems around here with pthread_cond_wait. The glibc version
we were using was used a linuxthreads snapshot taken at a bad time.
Pthread_cond_wait checked that the current thread owned the mutex.
Unfortunately, it did so even for "fast" mutexes, for which the owner field
wasn't set.
If this is the problem, I would guess that you should be able to avoid it by
using recursive or checking mutexes. The problem is hopefully very
temporary, since the glibc on sourceware exhibited this problem for only a
day.
