auto-revert-mode does what it does later, not at the moment Emacs gets
focus. I believe that at the moment when Emacs gets focus it should for all
files that are visited in buffers and changed outside of Emacs should ask:

     "File AA.C has changed on disk. Do you want to reload it?"

I think a popup should be used for this since it is more visible. Emacs
should also keep track of when this question was asked last time (to avoid
asking to many times).

After this the usual Emacs handling of the situation should persist.
