//  1. Never "return" from the critical section.
//  2. Never "SendMessage" or "Yield" from the critical section.
//  3. Never call USER API which may yield.
//  4. Always make the critical section as small as possible.
//  5. Critical sections in Win95 block across processes.  In NT
//     they are per-process only, so use mutexes instead.
