Hmm, I wanted to implement something with file notifications.

However, surprisingly this problem is reproducible in Emacs 23, but it
is NOT reproducible with Emacs 24.3.50. This is because
`revert-buffer-function' is set to `revert-buffer--default' since last
year.

My analysis was wrong, but the result (not a bug) is somehow right for
Emacs 24.3. We shall changed that to "Fixed in 24.4", 'tho.

Best regards, Michael.
