That's a big block size. bs=8k is interesting too because we see the

Hi,
As I would rather have something working we can base on in the
tree, so whoever volunteers for the refactoring (hint!) knows how
to design the interfaces, I am not sure how much is reasonable

will basically have to break migration. There is no way we can change
all the internal state and structure and maintain binary
compatibility with the old save states.
On the other hand it would be a *real* pity to drag
