bug#1681: 23.0.60; list-processes - please reset focus to original frame when done

We might be able to make such behavior customizable for the case where
Emacs asks for user input.  Meanwhile you could try using a workaround
like

(defvar my-selected-frame nil)

(add-hook 'temp-buffer-setup-hook
	  (lambda ()
	    (setq my-selected-frame (selected-frame))))

(add-hook 'post-command-hook
	  (lambda ()
	    (when my-selected-frame
	      (select-frame-set-input-focus my-selected-frame)
	      (setq my-selected-frame nil))))
