In support of 'no timeouts at TCP layer':

The first explanation I ever heard of TCP/IP was that it was designed 
(for DOD) to survive battle conditions where connections were expected to 
break and later be restored.

I then used someone's Telnet which broke a session after 15 minutes
without keystrokes.
