If a client socket is remotely lost but the client is not sent an RST in response to the next request, the socket might sit in RTO for extended lengths of time, resulting in "no internet" for users. Instead, timeout after 10s, which will close the underlying socket, recovering from the situation more promptly. Updates #10967 Signed-off-by: James Tucker <james@tailscale.com>
