-- A ddl operation shoud fail before trying to lock a ddl latch
-- in a multi-statement transaction.
-- If operation tries to lock already an locked latch then the
-- current transaction will be silently rolled back under our feet.
-- This is confusing. So check for multi-statement transaction
-- before locking the latch.
