IMHO the right solution is to stop exploding loose objects, and instead
write them all into a "cruft" pack. That's more efficient, to boot
(since it doesn't waste inodes, and may even retain deltas between cruft
objects).

But there are some tricks around timestamps. I wrote up some thoughts
in:

and downthread from there.
