We have an applications with multiple processes sharing mutex
semaphores.  Recently we had a problem where one of the processes 
would occasionally trap and abort that process.  (We have since fixed 
that problem.)  If it happened to own a semaphore when it died, all the 
other processes could not use that semaphore, since they would receive 
an error #105 (ERROR_SEM_OWNER_DIED).

Is there any way to create the semaphore such that if its owner dies, it 
is released automatically?  In our case, this might be helfpul.


Thanks for any answers... - Keith
