It sounds like we're actually talking about different things -- it
seems like you're talking about a large blk protocol architecture
rewrite, whereas I think I had always intended this just to be about
multi-page blk rings, as that was percieved to be a scalability
limitation.  If the multi-page aspect will turn up within a few months
of the 4.3 release, I think that still counts as a success for this
item.

If that aspect looks good, can we mark this one as "Good" instead of "Fair"?
