I ran a scrub on a Solaris 10 update 8 system yesterday and it is 100%

scrub: scrub in progress for 23h57m, 100.00% done, 0h0m to go
If blocks that have already been visited are freed and new blocks are
allocated, the seen:allocated ratio is no longer an accurate estimate
of how much more work is needed to complete the scrub.
Before the scrub prefetch code went in, I would routinely see scrubs
last 75 hours which had claimed to be "100.00% done" for over a day.
Interesting comparison, yesterday's scrub counted down from about 25
hours to go, today's is reporting:
scrub: scrub in progress for 7h36m, 15.86% done, 40h22m to go
Not much has changed in the pool over night.
