[mod_python] mod_python executing old versions of my code

When faced with the reload problem a few years ago, I created a special 
"reload" request. The request would list all the .py[oc] files in the 
script folder, and tries to unload or reload() each of them.

As a result, the "main" modules as well as dependent modules will have 
been reloaded or removed (At least, the ones that came from my project - 
it would not make sense to unload modules like 'os').

So just sending "http://myhost/pu/reload" to the server would cause the 
next request to get all new scripts.

I even used this on the production server after uploading updates.
