If the client has lost control of the transport, then it has no control
over what the data server sees and when. It can process the client's
write RPC 5 minutes from now, and it will never know.
THAT is what is absurd about the whole "the client MUST NOT send..."
shebang.
THAT is why there is no guarantee.
