Well, I switched from the heater that doesn't work and is poorly
documented (gvinum) to the one that does and  is (zfs, albeit mostly
documented by Sun), and so far I am warm :-)

Once I'd increased kmem, at least. I did get a panic before that, but
now I am shuffling data happily and slightly faster than gvinum did, and
memory has levelled off at about 160MB for zfs. I'll be keeping my
previous hardware RAID in one piece for a little while though, I think,
just in case! (old Adaptec card with a 2TB limit on containers).
