When the client shuts down its sending side, sockmap() shuts down the
server's in turn, and once the server has answered and closed, poll()
reports a hang-up on its socket. A socket sockmap() had nothing to ask
of at that moment, its buffer being full for a slow client, was still
polled, and a hang-up there ended both directions: whatever of the
answer was still unread in the kernel was dropped and the client got an
end of stream in the middle of it, megabytes short with large answers.
A hang-up on such a socket now only marks it: what is left is read
once the buffer has room, up to the end of the stream as usual. Errors
still end the connection. Since poll() reports a hang-up whatever is
asked, the socket is left out of poll() while nothing is asked of it.
The same holds for the client's side, for an upload cut short after the
server half-closes.
