It's not primarily pack-objects, I think. It's the rev-list that's run
by upload-pack.  Running "git rev-list --objects --all" on that repo
eats about 2G RSS, easily killing the system's cache on a small box,
leading to swapping and a painful time reading the packfile contents
afterwards to send them to the client.
