I'm not sure that inotify signals that a queue could be reused. It must
be arranged by the client. inotify(7) says

       Note that the event queue can overflow.  In this case, events are lost.
       Robust applications should handle the possibility of lost events grace‐
       fully.   For example, it may be necessary to rebuild part or all of the
       application cache.  (One simple, but possibly expensive, approach is to
       close  the  inotify file descriptor, empty the cache, create a new ino‐
       tify file descriptor, and then re-create watches and cache entries  for
       the objects to be monitored.)

This means, that a watch object returned by `file-notify-add-watch'
cannot be reused.

Let's first inform filenotify clients, that a watch is not valid
anymore. This gives them already valuable information.

Best regards, Michael.
