In v2 Ian asked (<21888.2988.774072.32...@mariner.uk.xensource.com>):
In the pdf

linked from the wiki page

it says that the secondary keeps a copy of the original contents of
its dirty pages. So I don't understand why you need to send the dirty
bitmap to the primary.
Which I don't see an answer for in my archive. Have I missed (or
misplaced) the answer?
