+ * 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)).
