[mod_python] How to stop reimporting modules

Hi,

This is an interesting issue - I have my own handler but I have a 
problem where mod_python does NOT cause modules to be reloaded - despite 
having changed on the disk I would have expected the module to 
reload...but it stays the same until I restart the web server - perhaps 
there is something Im doing wrong!!

I really dont want to restart the apache server to upgrade my software - 
it kills all current sessions and downloads....

Any ideas?

Cheers,
Barry
