Hello Arnd,

Thanks for the detailed reply. However, I doubt that removing and 
open-coding counting semaphores is the best alternative. Counting 
semaphores are a useful abstraction. I think open-coding counting 
semaphores everywhere counting semaphores are used would be a step back 
instead of a step forward.

Bart.
