I think you missed the part where he said that he wanted RAID level 1
(mirroring, not striping) protection so that his system wouldn't crash due
to a disk failure (of a disk containing swap space).
I'm pretty sure, though, that it's documented somewhere that swapping on a
MD RAID'd partition won't work due to potential deadlock allocating memory...
