You were lucky. ssh does that by default, so if ssh sessions are getting 
killed these days it's because the firewall ignores tcp keepalives when 
calculating timeouts. If you're in such an environment and can't fix the 
firewall, then every application needs to be written to explicitly
exchange data when idle to keep connections alive.
