Scrub from GUI not completing

[ProtoSD]

Normally I run scrub from the command line and it pretty consistently takes 12.5 hours. I decided to try it from the GUI this time. After giving it some time to get an accurate estimate of completion time, it reported it would complete in about 12.5 hours. At 12.5 hours I did a zpool status -v from the command line and it said 100% complete 0 minutes remaining, but there was still disk activity and the scrub status never said completed or the health was ok etc. Now it has been 14.5 hours, more than a scrub has ever taken to complete and it's STILL running.

# zpool status -v
pool: cortex
state: ONLINE
scrub: scrub in progress for 14h26m, 100.00% done, 0h0m to go
config:

NAME STATE READ WRITE CKSUM
cortex ONLINE 0 0 0
raidz2 ONLINE 0 0 0
gpt/ada0 ONLINE 0 0 0
gpt/ada1 ONLINE 0 0 0
gpt/ada2 ONLINE 0 0 0
gpt/ada3 ONLINE 0 0 0
gpt/ada4 ONLINE 0 0 0

After 15 hours I ended up aborting it 'zpool scrub -s cortex'. This is a 5 disk raidz2

Also, using 8.02 / AMD64

Ok, so just for comparison I did another scrub starting last night and initiated it from the command line. It finished in just under 13 hours, probably took a little longer than the normal 12.5 because I had to copy some files while it was working. Here's the output:

pool: cortex
state: ONLINE
scrub: scrub completed after 12h57m with 0 errors on Tue Oct 25 14:00:39 2011

FWIW, There is no differentiation at all between launching scrub from CLI or GUI
