Use `django-supervisor` to manage processes consistently during development and on production.

* Define all your processes in `supervisord.conf`.
* Run them all with `manage.py supervisor`.
* During development, you'll get auto-reloading for all processes.
* Specify the `interface:port` to bind to with the `SUPERVISOR` setting. The
  default is `127.0.0.1:8000` (localhost only) or `0.0.0.0:8000` (all
  interfaces) when extending the `develop` module from `ixc-settings`.
* Use `gunicorn` in development and on production.
