-- Very basic single user testing of row 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
