I am about to start fooling with semaphores for a program I am working on
and have run across something that bothers me.  There is no opposite to
InitSemaphore() that I can find.  When my program wants to exit, which
includes closing down the semaphore, what do I do?  Is it `safe' to simply
drop the semaphore if all ObtainSemaphore()s have been matched by an equal
number of ReleaseSemaphore()s?  This will be a private semaphore so I don't
have to worry about removing it from the system lists, or at least so it
would seem.
