[mod_python] Reload scripts without restarting Apache?

I'm getting started doing some development with mod_python, and I 
generally like to do a little bit at a time and test. That's made more 
difficult by having to restart Apache to get my new scripts used, and it 
would probably be worse on a production server. I don't want to lose 
performance, but is there  a way to make mod_python check if the script 
has changed or something?
