Just to add more info... I don't think write cache has anything to do 
with it because

1. dump is read-only.

2. 'dump 0fhs /dev/null 0 1048576 /usr' takes a half hour, but 'dump 0fs 
/dev/null 1048576 /usr' takes 15 seconds (remember, we're only 
interested in getting the estimate at the end of Pass II).

I've opened a PR.
