Great, please post that. But let's get this cleanup out of the way
first. It's OK if we have to go back and forth a bit if it means
we can avoid dependencies between the patches as this is already
all over the place.

Yes please post the patches rebased on testing-cleanup branch that I
just pushed. That branch is not immutable yet though as we're waiting
to hear from Arnd regrading the first patch in the branch.

Let's first nail down the cleanup changes though..
