I'm seeing CPU load on my ZFS test system being at 2.00 when it is
completely idle (2 cores). CPU is showing 99.9% idle, 0.0% iowait. If
I do:
/etc/init.d/zfsload stop
the cpu load falls down to 0.

Starting the zfsload service makes it go back up to 2.

Bug?

Thanks for the cross-check. At least it sounds like it's a consistently
reproducible bug.
