But these approaches don't really answer his question, which is a way 
to detect when a thread finishes.  This seems to be a trickier problem. 
 One way is to use a Timer to check the State property from time to 
time.  Or perhaps one could do some trick with a semaphore so that one 
thread is blocked until the specific thread releases the semaphore.
