This won't help. The TCP connection is already being closed (or I
think only half-closed). The problem is that in the Unix socket API
you don't find out about that unless you check or try to read or write
to it.

The tcp_keepalive setting would only come into play if the remote
machine crashed or was disconnected from the network.
