The proportion between time and commits may have something to do with
reachability test, where we traverse all commits and trees (I think
twice in git-gc, one when it runs "reflog expire" and one "prune").
packv4 is supposed to make tree traversing faster. Although it'd be
best if we could avoid this test.
