So, the proposal is to create an index of young objects without doing
reachability analysis (I still didn't get the point of packing them;
as I pointed out, it seems to be rather counter-productive) to help
the actual packing? From what I vaguely understood:
1. Index all the young objects to save a history traversal (?)
2. Perform the reachability analysis using the index in step 1, and
then generate the pack.
I'm not yet clear about what information 1 contains to help 2. Is it
the rough ordering? (The big important objects come near the top of
the pack, and the deltas are generated against them). I say "rough"
because the ordering might change after the unreachable objects are
