Putting your swap on a RAID'd partition _should_ theoretically provide the
best protection, but unfortunately, the way that software RAID handles
re-synching (after loss of a disk, or simply after an unclean shutdown), it
is not safe. You could consider this a bug or a design fault, but either
way it rules out swapping on software RAID.
This problem really only came to light recently. Therefore the FAQ was
written without knowledge of the problem...
