this starts up two servers - HTTP serving the django application on port 8000 and a port 8001 server that will start an interactive interpreter with any incoming connections. this enables you to have an interpreter in the same process as your server.

$ wget http://localhost:8000/someurl/
(...)
$ nc localhost 8001

This is ridiculously cool, but is there an advantage to doing it like this over just using "./manage.py shell"? Django servers don't really have any global state, so I'm not sure how useful it is being able to operate in the same process as the server itself.
