- * Win32 implementation of mutexes. Here we use critical sections as
- * our mutexes. We could have used mutexes, but mutexes are heavier
- * weight than critical sections. Mutexes and critical sections are
- * semantically identical, the only difference being that mutexes
- * can operate between processes (i.e. address spaces).
- *
- * It's worth noting that the Win32 functions supporting critical
- * sections do not provide any error information whatsoever (i.e.
- * all critical section routines return (void)).
