[Twisted-Python] reactor.stop() and deferToThead

[Dan]

Python seems to intentionally make aborting threads nigh impossible. You're
probably way better off doing something akin to this:

    def stuff2():
        time.sleep(4)
        if reactor.running:
            print "stuff2 finished"
        else:
            print "Don't need to stuff2"

Also iirc in Twisted you need to use callFromThread on reactor methods
rather than calling the reactor directly.
