I have a process that takes a list of URLs, uses client.getPage() to
retrieve the data, writes the contents to disk, and then moves the
file to another directory.

   # get feed list - this is a list tuples
    # url, name, username, password
    url_tuples = feed_list(feed_file)

    global C_URLS
    d =  defer.succeed(log_start(log))

    for tup_url in url_tuples:
        C_URLS += 1

        d.addCallback(get_page, tup_url)
        d.addErrback(get_page_error, tup_url[0])

        d.addCallback(page_to_file, tup_url)
        d.addErrback(page_to_file_error)

        d.addCallback(file_to_rsync_queue)
        d.addErrback(file_to_rsync_queue)

        d.addCallback(stop_working)
        #d.addErrback(self.gotError, (feed[0], 'while stopping'))

    reactor.run()

I want to put this into a loop and run it as a daemon, but the looping
is causing me a problem.  I've tried making the above into a procedure
(minus the stop working call back and reactor.run())  and it does not
run.  Any suggestions on how to encapsulate this into loop would be
gratefully appreciated.
