ij> -- Very basic single user testing of table locking, verify that the right locks
-- are obtained for simple operations.  This test only looks at table and
-- row logical locks, it does not verify physical latches or lock ordering.
--
-- The basic methodology is:
--    start transaction
--    simple operation
--    print lock table which should match the master
--    end transation
--
