All references I read today say that pthread_mutex (on which supposedly 
TCriticalSection is based) and the appropriate Windows stuff does 
contain an MB. But there might be issues with other OSes and Archs.

If they would not do so, the complete plain old threaded application 
paradigm would be invalid, and tons of applications would need to be 
trashed.
