 Instead of leaving unreachable objects in loose form when packing,
 or ejecting them into loose form when repacking, gather them in a
 packfile with an auxiliary file that records the last-use time of
 these objects.

 Expecting a reroll.

Feel free to eject this for the time being, especially if it makes
managing your tree any more convenient. I have a few small things that I
want to adjust before sending a new version, which likely won't happen
until after we have finished the 2.35 cycle.

Thanks,
