Kirti sent v7 a week ago, so I would have expected a revision based on that rather than a re-write based on v6 plus incorporation of a few of Kirti's patches directly. I liked the last version of these changes a lot, but we need to figure out how to combine development because we do not have infinite cycles for review available :-\ Thanks!
