Reload django wsgi scripts without root
If you are running mod_wsgi in daemon mode with apache, you may not have to restart apache to get it to reload.
I just touch my wsgi file (unix: touch updates the 'saved date' of a file) and apache reloads it on next access/web-hit.
See http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide
... as long as you can alter the timestamp on the WSGI script.

This article about reloading source code with mod_wsgi goes into how to reload source code, and even how to create a monitor script to automatically reload the daemon when you make source changes. It's really good for setting up a development environment using mod_wsgi.
