I think that you should not put the sys.exit(1) call, after the
reactor.stop() call.
>From my very limited understanding of how Twisted reactor works, it could be
done with something like:
statusCode = 1 #or whatever
reactor.stop()
in the method that stops the reactor
and the exit call should be added where (after) the reactor is started:
reactor.run()
# this will be executed after reactor stops
sys.exit(statusCode)
Please, correct me if I write nonsense here.
