[mod_python] Modules not reloading when changed

Unfortunately, mod_python has no way of controlling what modules your
scripts will be importing and making them reload.

There are a few ways to force a reload of modules that have changed and
are imported "indirectly":

1. The obvious - restart the server. 

2. The not so obvious - invoke the module that needs reloading directly
via a URL.  This will produce an error, but will force the module to
reload. This doesn't work too well when the module is not in one of the
WWW accessible directories because you will get a "File not found".

Another catch with this approach is that you will have to do this as many
times as there are apache server processes currently running.

3. Recommended approach. Create a debug flag in your scripts and do a
reload when it is on:

DEBUG = 1

import mymodulea
import mymoduleb
import string
import cgi

if DEBUG:
	mymodulea = reload(mymodulea)
	mymoduleb = reload(mymoduleb)

When you're done debugging, you set DEBUG to 0 or None.
