Actually, now that you mention it, I've just added this to my .emacs:

(defadvice other-window (before one-window-p activate)
   "If there are no other windows, signal an error."
   (when (one-window-p)
     (error "No other windows")))

(defadvice other-frame (before one-frame-p activate)
   "If there are no other frames, signal an error."
   (when (= (length (frame-list)) 1)
     (error "No other frames")))

(setq debug-ignored-errors
       (cons "\\`No other \\(window\\|frame\\)s\\'" debug-ignored-errors))
