Apart from counting behaviour the biggest differnce is in
scope of mutex and semaphore. Mutex have process scope that
is it is valid within a process space and can be used for
thread synchronization (hence light weight), semaphore are
can be used accross process space and hence can be used for
inter process synch.
However on RTOS this distinction is not applicable due to
flat process space hence only semaphores are supported on
typical RTOS.
