Note that semaphores are associated with a process and not a thread
and thus can't be used to detect the death of a thread.  If the
thread terminates cleanly, you can have it send a message to a queue
announcing its demise.  You can have a separate thread waiting on the
queue that frees the resources for the departed tthreads.
