I had a vague notion that the subproject could hold _both_ of them, since it's really the commits you're flipping between. But obviously that has quite complex semantics, so now it's me doing the handwaving.

What is the planned behavior when doing such a switch? I.e., if I have kernel/ bound to linux-2.6, and I do a 'git-checkout' back in time to a version that wants linux-2.4 bound at kernel/, what will happen? Blowing away my subproject repo doesn't seem right.
