I beg to differ on this one. Having spend several weeks tracking down random processes dying on a
machine that turned out to be a bad sector in the swap partition, I have had great results by
running swap on a RAID-1. If you develop a bad sector in a non-mirrored swap, bad things happen
indeterminately and can be a royal PITA to chase down. It's just a little extra piece of mind.

Brad
