predates RAID. If you just split your swap across multiple drives, you
get RAID0 behavior from swap.

Really? I thought it was possible to interleave multiple swap devices.
I'm probably wrong, but I thought I remembered seeing 'interleaved'
somewhere. Maybe my definition of interleaved is differented from
someone elses :-)
