-// We go over the list of promoted objects, removing each from the list,
-// and applying the closure (this may, in turn, add more elements to
-// the tail of the promoted list, and these newly added objects will
-// also be processed) until the list is empty.
-// To aid verification and debugging, in the non-product builds
-// we actually forward _promoHead each time we process a promoted oop.
-// Note that this is not necessary in general (i.e. when we don't need to
-// call PromotionInfo::verify()) because oop_iterate can only add to the
-// end of _promoTail, and never needs to look at _promoHead.
