Everyone would need to restart and probably reapply they changes on top
of new tree (because of lack of common history).

linux-2.6.git is all about lots of small changes so size isn't all that
big today but there are quite many objects. Using grafts might help
decreasing size of repository. I just mentioned it because it is a bit
of a revolution time anyway and otherwise current tree will grow for next
decade or so.

It's just an idea, I'm happy either way.
