That's what exit() does.  I don't think we really care unless the leak
is inside a loop.

That being said, it's untidy and is setting a poor example so I guess
we should fix it.

It would be better to just send the patch rather than preceding it
with "can I send a patch".  Everyone can send a patch and they are
encouraged to do so!
