This only enables keep-alive with the default timeout. That may very well be
(far) too long to make any difference to you.

In Linux, you can also set TCP_KEEPIDLE and TCP_KEEPINTVL to alter the
behavior on a per-connection basis, but it seems that in MacOS X you need to
instead use sysctl and change these globally. As described at
http://www.gnugk.org/keepalive.html

At least I couldn't find any other ways.
