That would be good.  Quite generally, those windows/frames that are created (e.g. via pop-to-buffer) for a specific window should be removed after we're done with the interaction (see also quit-window).   I've had a kludge for this in Aquamacs for a long time (via an advice to bury-buffer), but it's quite difficult to do consistently when Emacs and 3rd-part packages aren't aware that this is happening.

Are dedicated windows the way to go?
