The schema server answered the 8th undecodable frame and ended the peer's session in the same
call; ending clears the session's pending reliable packets, so a lost datagram was never
resent. The session now stays until the peer has acknowledged every answer (a lost one is
resent by PollResends) or a 2 s grace runs out, serves nothing after the capped frame
meanwhile, and then sends the goodbye.
