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.
