Right-o. And you don't have to even assume it, it's documented that
Wait() clears signals and GetMsg() doesn't do anything to signals.

The CLOSEWINDOW message sets the signal, you read it before looking
at the signal, then when you go to check the signal with a Wait() it
returns immediately because the signal is set but the message has already 
been processed hence the null return from GetMsg().
