If it doesn't then there is a bug.  Each client remembers the OIDs
of objects it has seen during a transaction.  When the client tries
to commit, it first receives a set of invalid OIDs from the server
(OIDs for objects that have been changed in the DB).  If any of
those OIDs have been seen then a conflict error is raised.
