IMO, this is a bug in macOS: the kqueue feature is incomplete and
unreliable.  I suggest to file a bug report with kqueue developers
about that.  I don't see how Emacs can do anything to improve the
situation on macOS regarding file notifications, as long as macOS
doesn't get their act together and fix this.
