I'm not really across this stuff enough to comment much, you've
clearly thought about it a lot more than most people.

Having said that I'm a tad wary of any format involves reading/writing
in its entirety.

On the wiki you quote hg, which reads a Dirstate for 19470 files in
220ms. If it scales linearly that'd mean ~23.6 seconds just to read
the state for my ~2 million file repository. Am I reading that right?
