Actually, as VM changes so frequently, I don't know just what the present cache replacement policy is; maybe it's already sweep resistant; my point is that early writing isn't about that.
Early writing makes it so all those page frames wasted with pages that will never be used again are at least clean, so when they do get reclaimed, the reclaimer doesn't have to wait. The wait for page laundry is shifted to the guy diryting pages away from the innocent bystander competing for real memory.
