Do I really need these annotations to be wrapped in weak refs?
Wouldn't they get immediately gced?

Or if I just leave them strong, my whole Key instance will be gc candidate the moment I nullify it in here

  |          ((KeyRef) ref).key = null;
  |       }

since nothing else now has a strongly ref on it.
