Not the improvement I had hoped. Your verify-pack ran much more
quickly than the fsck I was seeing that led me to suggest this to
Junio a few weeks ago. But saving a minute is still pretty good.

That index-pack run is basically what we get during clone, so
I don't really expect to improve on that. (However I have been
contemplating that the locality within the pack isn't optimal and
we can do better placement.)
