The only reliable way is to restart the whole of Apache.

If it were a development server, you could also use the brute force
method of having the Apache child process restart after every request.
This is done using the Apache directive:

  MaxRequestsPerChild 1

This should however never be used on a production server, as it would
give CGI like performance.

In short, there is no good way of doing it. Even the module importer
in 3.3.1 is only of use to web application code which is managed by
mod_python and not normal Python modules on sys.path.
