For each lock you are creating handles without closing them (leaks) and 
connecting by name for each lock is also pretty inefficient. CloseHandle 
in the destructor is useless, as no one is going to call it as users 
will just remove shared memory. Mutex names are local and can't be seen 
by other users/services....

Believe me, using native calls to emulate process-shared pthreads is not 
that easy.
