Unrelated topic: We may also want to consider doing the reverse, that is symlink '.git/refs/borrows-from' of the cloned repository to '.git/refs' in the original repository. This way pushing into the cloned repository can avoid uploading objects which the cloned repository already has access to via its objects/info/alternates setup.

This would especially be nice with project forks, such as on repo.or.cz. I don't need to upload all of 'master' if it has already been uploaded by pasky's mirror job, for example.
