> SASL enforces its own message ordering. When RPC server sends its responses back, response
A may be wrapped by SASL before response B but is put on response queue after response B.
This results in RPC client receiving wrapped response B ahead of A. When the received messages
are unwrapped by SASL, SASL complaints the messages are out of order.
