That's interesting.

Hmmm, looking again at the implementation of select(), I don't immediately see 
that when waiting on /dev/windows, it checks that the message queue has old 
messages on it before waiting.  The MSDN documentation for 
MsgWaitForMultipleObjects() seems to says that messages which had arrived 
before the last PeekMessage() etc. aren't considered new and so don't end the 
wait?  But I could easily be missing something...
