[mod_python] How can I turn off apparent caching of python code?

What's more it does not always work.  The docs on
the reload() function reveal that many of the changes
that I make to a module will not have any effect.

If I change the name of a class for instance, the
old one still exists until the apache server is restarted.

So, is there any way at all that I can avoid caching python
objects entirely while developing?

Thanks
