[Message part 1 (text/plain, inline)]

Thanks for the pointer Michael.

I am puzzled. Of course filenotify does not work for me (it used to work; I
wrote this elisp snippet that used this feature:
http://emacs.stackexchange.com/a/2566/115).

The value of `file-notify--library` is `'gfilenotify` but the feature
doesn't work for me. Any pointers?

The test code evalling did not trigger the `my-notify-callback` function
and so no "Event .." messages in my *Messages* buffer.
