But I recently encountered some problems with pthread_cond_broadcast (no ticket yet since I haven't pinpointed it exactly). In a very simple C# 
Hello
World app Mono checks for the pthread_cond_broadcast return codes and asserts that they are zero (I assume it runs single-threaded, no Garbage 
Collector). If I remove Mono's asserts it works as expected. The
problematic
return code is EINVAL iirc (B_BAD_VALUE), and I traced it to libroot's release_sem_etc, triggered by "if (count <= 0 && (flags & B_RELEASE_ALL) 
==
0) return B_BAD_VALUE;".


The condition variable implementation looks indeed not correct -- a
pthread_cond_broadcast() should [not] return an error when no one is waiting. I'll 
have a closer look.


Thanks for your fix! My Hello World runs fine now at r27263.
