What happens on w32 when a watched directory is deleted is that the
thread which watches the changes exits (with an abnormal status), but
the object created to watch the changes still exists, and can be
easily tested for being "invalid".

So if you want to implement file-notify-valid-p, go ahead; the w32
side will be almost trivial.
