Description Dmitrij Tejblum 2005-01-20 15:00:40 UTC 
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.

How-To-Repeat: 
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.
