Perhaps I don't quite understand your needs, but the standard 
Semaphore object in the threading module claims to support counting:

http://docs.python.org/lib/semaphore-objects.html

I haven't used it myself yet but the Python docs have never promised 
me anything that didn't work as described (yay!).  I guess I must be 
missing something.
