There are lots of nice examples in the Twisted documentation on how to write a server but I can't seem to find anywhere that making it daemonize is mentioned. All the examples hold onto the terminal after reactor.run() is called. If I want a Twisted server to return the terminal and run as a daemon how would I accomplish that aside from starting it with nohup?

You'd write a .tac file and run it with "twistd -y [tac file]".

The documentation is at http://twistedmatrix.com/documents/current/howto/application but is terse and desperately short on examples.

Several of the examples use that setup:

http://twistedmatrix.com/documents/current/examples/chatserver.py http://twistedmatrix.com/documents/current/examples/emailserver.py

At the end of the tutorial intro, the finger code is converted to a tac file too: http://twistedmatrix.com/documents/current/howto/tutorial/intro

The crucial step is creating the object called 'application' at the global level -- this is what twistd seeks.
