Django snippets: server with debugging backdoor

#!/usr/bin/env python

import os

from django.core.handlers.wsgi import WSGIHandler
from eventlet import api, backdoor, wsgi

os.environ["DJANGO_SETTINGS_MODULE"] = "settings"

api.spawn(api.tcp_server, api.tcp_listener(("127.0.0.1", 8001)), backdoor.backdoor)

wsgi.server(api.tcp_listener(("127.0.0.1", 8000)), WSGIHandler())

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.
