No, and RDBMS update or insert does *not* cause the zodb to
grow (unless zodb data is changed at the same time).

Perhaps you are confusing current-transaction-rollback and Undo?
Zope supports the former with RDBs, but not the latter.  That is,
once the transaction is *comitted*, it can't be rolled back by Zope.
Might be a nice feature to add, though, for databases that support
it <grin>.
