Yep, the mutex has already been cleaned up. It is the mutex unlock operation that fails. This is termination (ungraceful). We don't wait for worker threads to terminate; sometimes the main thread has cleaned up pchild and bailed by the time the worker threads get dispatched from the interrupt-all and then release the mutex. -- Jeff Trawick | [EMAIL PROTECTED] Born in Roswell... married an alien...
