Using twistd -y is a good way to daemonise your Twisted program, but the -y
option takes a “TAC” file, not just any Python file.  They are briefly
described, including an example, here:
<http://twistedmatrix.com/documents/current/core/howto/application.html#auto5>

The really short version is rather than calling reactor methods like
reactor.connectTCP directly, you create a bunch of service objects that will do
those things when started, and attach those to an Application instance called
“application”.  That's a TAC file.
