Because one of the RAID1 OS disks failed (System #1), I replaced both
disks and downgraded to stable/8. Two hours ago I submitted a job. 

I noticed on boot smartd issued warnings about disk firmware, which I'll
update this coming weekend, unless the system hangs before then. 

I first want to see if that system will also hang under 8.3. I have
noticed a looping "ls" of the target ZFS directory is MUCH snappier
under 8.3 than 9.x. 

My CentOS 6.3 ZFS-on-Linux system (System #3) is crunching along (24
hours now). This system under stable/9 would previously spontaneously
reboot whenever I sent a ZFS data set too it.

System #2 is hung (stable/9).
