It is not a mechanism suitable for 1-n publisher-subscriber or
multi-cast services (you were talking about messaging). Think of various
scenarios when some of consumer/producer tasks die or get blocked.
Semaphore is a too low-level primitive and with k>1 has almost no
practical use.

Otherwise, your code works as expected.
