[Twisted-Python] stopFactory() called twice

[Nicholas Piper]

radix suggested I report this to the mailing list. It happens both
with CVS and 0.16.0

Example output from my program is:

(own == one wire network)

My code is very messy and bad probably :-) and my threads are probably
quite dangerous. It can be found at
www.nickpiper.co.uk/ibutton/play.py for the next few days.
