It did used to do this (that's where I got the idea from ;), but there's not
much sign of it anymore.  There's a global 'interruptCountdown' in
twisted.internet.main, but it's no longer used anywhere that I can find.
I'm guessing that in the great Reactor Refactor, or the Bride of Reactor
Refactor, this feature went AWOL...

Who wants to have this bug assigned to them?  :)
