src/objects.cc:6058: copy = isolate->factory()->CopyJSObjectWithMemento(object,
site_to_pass);
I think this method should be called CopyJSObjectWithAllocationSite(), because
although it's true that mementos (there can be more than one when depth > 1) may
be emitted, the allocation site is really in charge. In fact, mementos could
become a thing of the past, and the tracking mechanism becomes maintained in
some other way.
