If you scrub only the live data, total scrub time becomes a function of used space as opposed to total space. But the main reason for asking was that I was thinking of situations where your appliance is not used but venti is. The illusion of a perfect array-of-bytes abstraction can't always be sustained in any case. Thanks to everyone who set me straight on fossil + venti.
