I was under the impression that the job of a CGI program was to load, run and 
exit, echoing the resultant HTML web page to stdout as it goes. It must run as 
quickly as possible, so your idea of it hanging around with some kind of 
mysterious ethereal connection to the browser that initiated it, will 
definitely *not work*. You can get the page itself to increment a number on it 
every second, using Javascript techniques. You can also use Javascript to 
"submit" the form when a key is pressed, thereby restarting your CGI app. Good 
luck.
