I have reread this and I think the general approach is fine. I'm
going to take the detailed semantics on trust.
Previously I asked:
I'd like some opinion from Andrew Cooper about whether he's happy with
the interleaving of the colo-specific functionality in the middle of
the restore code, as you have done it. Personally I think it seems
like it's probably the best way, but it may merit questioning, at
least.
Andrew has not replied to object. So I am content that we can
go forward with this approach.
