One approach I've read discussed is that the server maintain a list of
objects which have ever owned anything (objects, verbs, properties).
(This list will eventually contain objects which don't -presently- own
anything; that's fine.  This list should automatically be generated when
the server's started.)

When renumber() is called on object FOO, the server checks to see if FOO
(or the obnum to which FOO will be renumbered) is in the list of objects
which have ever owned anything (objects, verbs, properties), and if not,
it may be renumbered without walking through the whole database to repair
ownership.
