And there's no handle at all?  It's not important if it's not an event 
handle as long as it is an handle usable with WaitForMultipleObjects.

Also, I don't understand how it will be possible to implement 
threading.Event without using finally, at the lower level, a handle, 
since as far as I know this is the mechanisms the OS offers.

I wouldn't want to derive from Event since my goal would be to submit a 
patch to make subprocess.Popen.wait take an optional threading.Event to 
kill the process.
