On Linux, we set up our apps to catch SIGTERM:


import signal

def install_signal_handler(self):
    """install a handler for SIGTERM, providing clean shutdown"""
    def signal_handler(foo, bar):
        sys.stderr.write("Got SIGTERM, shutting down")
    return signal.signal(signal.SIGTERM, signal_handler)

where self is the object that takes over from your main().

IIRC Wing has a menu that allows sending signals to the debug process.  Using 
SIGTERM to mean please quit/exit/shutdown is standard UNIX - works with init 
scripts, kill/top, etc..
