WinNT4 -- don't have other platforms to hand.

If I hit Ctrl-C in the roundup-server console 
window, the resulting KeyboardInterrupt doesn't 
appear to be caught and acted on until the next 
HTTP request hits the server.

I suspect this is more a Python socket library 
problem -- my guess is that the KeyboardInterrupt 
doesn't interrupt socket.listen -- than a Roundup 
problem...
