Sorry, my email has been up and down today, I didn't read the message

All very true.  I think you'll also agree that it doesn't pose any 
particular danger during development.

If you're referring to the fact that Python's shutdown code (including 
calling atexit registered functions) don't get run in those instances, 
then I would agree that it "isn't wholly safe".

I'd also say that it isn't very smart to do that in a production 
environment, but we're talking about development, and I don't see a 
problem there (and haven't yet, as that's how I always shut down Zope 3 
on Windows)

Right.
