If running the Linux kernel, the keepalive timer behaviour can be tuned 
at runtime.

Tunable settings are documented here:
http://www.die.net/doc/linux/man/man7/tcp.7.html

So I could set the timer to kill TCP sockets which are no longer viable 
after a shorter period. This would keep the server pretty clear of 
stale, unwanted processes. That is so long as the Xlibs do implement 
SO_KEEPALIVE and that the Xlibs based programs do actually die when the 
socket is closed.
