They're still occupying disk, nicht wahr? You could possibly have two
methods, one to get the sum and one two get a mapping of version, size
where old object versions and undo info was considered a version.

As to waking up the objects, this seems necessary. On the other side, this
could be a scheduled task running once an hour or so. Would be useless to
users, but useful for accounting.
