Yes, however I can't figure out how could I use mutexes as counting 
semaphores, for instance. They have different meanings. However I could think 
in semaphores protected by PIP in singular cases, although I couldn't figure 
out how to do it in a systematic approach so that it could be used in a 
realtime framework such as Xenomai...

Rodrigo.
