I'm looking into CoreSessionTracking, and like what I see, but I've got a question. I want to have sessions persist beyond browser shut-off, which means I'll need a Session Data Container. In the docs, it's mentioned that the Data Container should be instantiated inside a non-undoing database. Well, I want to keep the undoability of the ZODB for most of my site, so how do I mount a non-undoable database somewhere in the tree? I've looked around at zope.org, and I've run into MountedStorage, but it seems to be out of date ("need a very recent CVS, the 2.2-pre releases aren't good enough," etc), so I'm wondering if there's a better way, or at least a Howto somewhere.
