Actually, that is normal, what you see are "spurious wake-ups" caused by
the signals sent by gdb, these are allowed by the posix specification.
However calling pthread_cond_wait again should not return immediately,
it should block until the call to pthread_cond_broadcast, so there
should not be a lockup.
