Well, the reasoning about the kernel being able to find stuff in swap if the partition was mirrored kind of makes sense. Where I work, we used to put use two separate partitions for swap. Whenever a disk went down, the box was likely to crash too and so we would find out about the disk after a reboot. After we made those partitions a mirror of one another for swap, we now don't get crashes and we get notifications of a disk going down.
