 Well the top bug didn't seem to resolve my actual issue and yes it it a
complete ZFS system.  Problem is that the HD activity indicator light is
constantly flickering even though should be minimal activity.  top still
shows no activity around the blinks, and there's no swapping happening
although gstat does seem to roughly match the blinks.  I can't tell what
your patch does, would it enable me to see what's touching the disk?
