In my particular case, data, sys and swap are all on separate hard
disks. The swap partition shares a drive which I use for archiving so it
sees little use and for all intents and purposes is its own disk.

I like that last idea, however I think the big problem is the
amount of data the kernel transfers to swap at once - like megs and megs
in one shot. The system freezes pretty hard during these massive swap
phases.
