Clean up idle TCP connections

[GoogleCodeExporter]

The server may need a way to recognize and clean "old" sockets that are not 
in use any more (i.e., client's TCP stack didn't send FIN packet).

Avner,
do you see necessity in additional command line option to enable keepalive 
capacity on request.
can SO_KEEPALIVE option be used to introduce this ability.

no need for additional command line switch.  This is standard behavior for a 
decent server.

(BTW, I think that on UNIX it may take SO_KEEPALIVE hours to recognize dead 
connection; hence, this soultion is not valid with conventional servers.  
Anyhow, this feature is low priority, hence, please ignore it at the moment)
