I think you can simplify this quite a bit to just:

  git clone --quiet git://git.busybox.net/buildroot

That breaks, but works without --quiet. Presumably the problem is on the server side, as we see the remote end hang up (and using different versions of git on the client does not seem to help).

It seems to fail consistently for me around 2.4s, which makes me think we're hitting some kind of timeout. I'd suspect a bug in the keep-alive code in upload-pack, but that shouldn't have kicked in by then.

I guess the next step is to try to reproduce with a local client/server, and then bisect the server version.
