Not in my system. Why you assume I'm using windows? :-) (In fact, AFAIK, 
windows does support
recursive mutexes). No, in my case they're implemented with a semaphore, so 
calling it twice in a row
in the same thread would deadlock. This is an embedded system, and the 
synchronization support
isn't very good. It's quite minimal. This is why I need to do it by myself.

Thanks.
