[mod_python] Session Cleanups - Still a mystery

Session cleanups should happen randomly with about 1 in 1000 chance (1 out
of 1000 session requests will trigger a cleanup). During a cleanup, all
expired sessions should get deleted from the dmb.

How big is the dmb getting that you are concerned with space?
