 * 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)).
