If I'm not mistaken you're thinking about this on the wrong level; the 
handling of the keep-alive option is internal to the operating system 
socket. Your Lua code doesn't receive any 'notifications' except an 
error when you try to use a socket that's been closed because of a 
timeout (despite having set the keep-alive option). That's it really.

PS. If you really were looking for how TCP keep-alive works you might 
find http://en.wikipedia.org/wiki/Keepalive#TCP_Keepalive a useful 
starting point.
