If a client doesn't send any data then we would leave the socket open
for as long as it needed, wasting resources. Add timeouts to limit the
amount of time this can happen for.
Since there is a limit on number of sockets that the server will have
queued, having idle sockets stick around forever is a vector for ddos.
Pick-to: 6.4
