[mod_python] How to keep globals

When I was asking about my database problems. Someone mentioned to me 
that they kept a single global database connection and just pulled 
cursers off that. And while I know how to do that in the context of a 
thick client add (we build a big app with wxPython), I'm not sure how to 
keep globals in apache other than using the session. I've seen lots of 
examples on the web but none of it seems to make much sense...

Cheers
