[mod_python] Force reload of all imported files on *every* request?

Is there a way with mod_python to force it to reload all imported files 
on every request?

It's a development server but I *cannot* edit httpd.conf and most other 
suggestions I've seen deal with restarting apache everytime I edit a 
file... that is to say the least cludgy.



Also, if I have a text block of code (reading it from the database) with 
a class definition and a single import (urllib) can I use exec() to 
declare that class and then use it? So I want to do this:


code = "my code is here, this is a class definition and an from urllib 
import urlopen statement"
exec(code)
myinst = MyClassName()



And yes, I'm a complete Python newbie. Thanks! :-P
