# Bug #12423 "Deadlock when doing FLUSH PRIVILEGES and GRANT in
# multi-threaded environment". We should be able to execute FLUSH
# PRIVILEGES and SET PASSWORD simultaneously with other account
# management commands (such as GRANT and REVOKE) without causing
# deadlocks. To achieve this we should ensure that all account
# management commands take table and internal locks in the same order.
