simplify matters usefully.
+1, my initial review-comment was probably badly phrased, the patch adds a 
complicated feature and it will take effort to learn these things for anyone 
working with the Cassandra code base, but I think it will be worth it in the end

bq. I'm not sure Marcus was performance testing.
no, not at all, just ran stress a couple of times to get ballpark numbers
