I forgot to mention that it would immediately respond if the clipboard 
has changed since the last time it responded.

You keep saying that without this a client can't see what is in the 
clipboard, but I'm reasonably certain a client at any time can query it, 
right? If not that should be added, but it is orthogonal to any 
clipboard-changed event.
