Read the man page *completely*.

	A  condition  variable  must  always be associated with a mutex, to 
avoid the race condition where a thread prepares to wait on a condition 
variable and another thread signals the  condition just before the first 
thread actually waits on it.

and:

	Before returning to the calling thread, !pthread_cond_wait! re-acquires 
|mutex| (as per !pthread_lock_mutex!).
