Yes, you are right, I misunderstood the use of condition varaibles. My
condition variables were initialized with a mutex all-right, but another
mutex that the one used by the function doing the wait(). I was not aware
that the condition varaible should actually be initialized with the mutex
that is used in the synchronization. 

My problem is now solved! Thanks to everyone who responded, and my
apollogies to Shinji - you vere right all the way!!!


Best regards,
