   May be usefull to add some simple workflow to Persistent class with
   states:
       GHOST
       UPTODATE
       CHANGED
       STICKY
   transitions:
       activate
       deactivate
       ghostify
       unghostify
       changed
       invalidate
       and others
   and to be able to add hooks to before and after transition.
