I have successfully used threads to implement a "Janitor" that periodically 
deletes expired sessions. It is (re)started when the module is imported. It 
is part of a session module that handles cookie based user session variables. 

from mod_python import apache
from session import CookieSession

def handler(req):
	sess = CookieSession(req)
		sess['hits'] += 1
	except KeyError:
		sess['hits'] = 1
	req.write("Session hits: "+str(sess['hits']))
	return apache.OK

Anyone interested in such a beast can drop me a line. I have not yet tested it 
extensively but Threads and Events definitely *seem* to work.

My setup:
apache 2.0.40
mod_python 3.0 BETA ( patched )
python 2.2.1
