+// The pthreads API has an initialization macro that has no correspondence to anything in
+// the windows API. By investigating the internal definition of the critical section type,
+// one may work out how to initialize one without calling InitializeCriticalSection().
+// The trick here is that InitializeCriticalSection() is not allowed to fail. It tries
+// to allocate a critical section debug object, but if no memory is available, it sets
+// the pointer to a specific value. (One would expect that value to be NULL, but it is
+// actually (void *)-1 for some reason.) Thus we can use this special value for that
+// pointer, and the critical section code will work.
+
+// The other important part of the critical section type to initialize is the number
+// of waiters. This controls whether or not the mutex is locked. Fortunately, this
+// part of the critical section is unlikely to change. Apparently, many programs
+// already test critical sections to see if they are locked using this value, so
+// Microsoft felt that it was necessary to keep it set at -1 for an unlocked critical
+// section, even when they changed the underlying algorithm to be more scalable.
+// The final parts of the critical section object are unimportant, and can be set
+// to zero for their defaults. This yields an initialization macro:
