I should be able to get http-pull down to the neighborhood of (current) ssh-pull; http-pull is that slow (when the source repository isn't packed) because it's entirely sequential, rather than overlapping requests like ssh-pull now does.
I should also be able to get ssh-pull down to the area of clone-pack, but that's lower-priority, since there's clone-pack.
(I've written an untested patch for local-pull, which I'll be testing, cleaning, and submitting tonight, assuming my newly-arrived monitor actually works)

I've noticed that ssh connections don't actually disconnect at the end with recent versions of ssh sometimes. In my experience, this occasionally happens with git, but always happens with scp, suggesting that it's an ssh bug of some sort; I've also only noticed this with openssh 3.9_p1 with some of Gentoo's -r2 patches.
