IPC::ClientConnection now tracks the time since the last time we got a message from the client and calls a virtual function on itself after 3 seconds: may_have_become_unresponsive(). Subclasses of ClientConnection can then react to this if they like. We use this mechanism in WindowServer to send out a friendly Ping message to the client. If he doesn't Pong within 1 second, we mark the client as "unresponsive" and recompose all of his windows with a darkened appearance and amended title until he Pongs us. This is a little on the aggressive side and we should figure out a way to wake up less often. Perhaps this could only be done to windows the user is currently interacting with, for example. Anyways, this is pretty cool! :^)
