Packing storage A would result in needing to re-sync the whole storage, 
wouldn't it? What would happen if storage B (the target storage) got 
packed? 

It seems to me like the way to do this would be to make sure the normal
clients of storage B are always in read-only mode... otherwise you're going
to be in a potential world of pain...
