When a TCP socket is shutdown for writing, but isn't closed and isn't shutdown
for reading, then keep-alives does not work on this socket.
Set sysctl net.inet.tcp.keepintvl to several seconds, create a half-closed
connection, and look with tcpdump. Half-closed connection may be create by
e.g. rsh -n.
I'll take this one.
