Gives some nice results for the "rev-list --all --objects" test on the
gentoo repo says (with the old pack):

Testing a full repack, it feels slower during the "Compressing objects"
part, but I don't have any hard numbers on that, and maybe I've just
been more patient the last week, when I did the first repack on that
repo. I can just tell that it took about 13 minutes for the "Compressing
objects" part, and 18 minutes in total, on my Core 2 Quad 2.83GHz with
4G of RAM.
The new pack is slightly worse than the old one (window=250, --depth=250):
Old: 759662467
New: 759720234
But that's seems totally negligible, and at least the performance of the
(stupid) rev-list test is not affected by the different pack layout.
