I wonder why you think the ZODB isn't the place to do this?

If it is because of the versioning issue:

1) You can create a special datastructure that doesn't version on every
commit, but instead perhaps every minute.  Think of it as halfway
between volatile and persistent.

2) One of these days we'll come out with a non-versioning Storage class,
plus allow people to mix Storages in the same process.

3) Then again, perhaps people could live with the 20 byte or so growth
on each Session commit.
