This is one of the main ideas behind medusa, to keep the server
running in a single process in order to make it easy to maintain
state.

Take a look at medusa/script_handler.py, and the files in the
script_handler_demo.py directory.

The main drawback with Medusa's 'CGI' model is that it can't be used
for processing that would 'block' the rest of the server. Processing
should be quick.

For example, building a medusa server around a bsddb works well, but
you can't (easily) make connections to an external SQL database,
process, or server where the queries might take on the order of
seconds.

To solve that problem, check out the eGroups coroutine stuff here:
