What would this be used for?  This is pretty hard to do for RDBMSs and other
psuedo transactional things, like LDAP connections and mail systems.

If we move toward a model where resoure managers keep track of object
changes, this gets even harder, although I suppose that the transaction
could delegate to the RMs.
