Actually what I meant was more like the traditional P and V
operations.  I wanted to be able to initialize a SEM to a count
and then have threads be able to P (request) the sem as many
times as the original count.  Used for controlling resources
that can have more than one and less than all users.

It turned out the code to implement counting semaphores in OS/2
was quite trivial.  It is just to bad that Microsoft didn't
include them in the first place.
