In multi keys operation like SUnion SInter ZUnion ZInter RpopLpush,
nemo code requests record lock with the input argument order.
For example,thread 1 locks on "Key1" then requests for "Key2",thread 2 locks on "Key2" requests for "Key1".Then dead lock occurs.
Thread mutex of record lock must be locked in the same order.
