I have been looking at running some twisted programs as a windows service.
So in the end I took a copy of twistd.py and adapted it to load my tac file
and run it as a windows service.
Of course the windows service will run it in a separate thread.
I now have it running on XP, 2003 Server Twisted 10 and 12 and it all
seemed fine.
However when I install it on Windows 7 I get an error
2012-10-23 07:54:49+0100 [-] Unhandled Error
Traceback (most recent call last):

Looking around it would seem I need to tell the reactor
'installsignalhandlers=0'. I am not sure if I should do this with windows
or not.
Has anyone got twistd.py to run as a service on windows because I would be
glad to know what other people have done to solve the problem.
Thanks for any info.
