Can you clarify? What else do you think we should check.
If its not a security negotiation message and we are expecting one the
message ends up being ignored. As the comment states in the ConnectionManager
code, we could enhance this to send a message back to the client for them to do
something smart, like possibly retry if somehow the message got corrupt.
