With async image loading,activelinks will be loaded too. As for the 21 secs. It can be decreased, but only to sacrifice something else. 21 sec means the client can skip a keepalive, and fail after the second. Since it's localhost, it's unlikely to fail even 1, so it can be reduced to 11 sec. If we send keepalives more frequently, it will consume more resources for all tabs to send them, but it will reduce further the time needed to detect tab closes. It is easily configured with constants though.
