I have problems with accumulating buffers because I use desktop.el
that remembers all file buffers and tries to restore them after restart.
Other users may have other problems with accumulating buffers.
I solved this problem for myself by adding to .emacs:

(define-key image-mode-map "q" 'quit-window-kill-buffer)
(define-key archive-mode-map "q" 'quit-window-kill-buffer)
(define-key tar-mode-map "q" 'quit-window-kill-buffer)
(define-key dired-mode-map "q" 'quit-window-kill-buffer)

Of course, we should not suggest users doing the same.
So perhaps a defcustom would be the best solution.
