      Description

      We could try to forward the object before we go ahead and retain the page. This could be an optimization in two cases:
      1) A mutator would avoid a relocation stall in case the page is claimed, but the object the mutator is interested in has already been relocated.
      2) The worker thread detaching the page would not have to wait for a mutator that is just forwarding an object.
