The interesting thing from other reports is that it appears to be kswapd
using up CPU resources. Not the swapout code at all. So it appears
to be a fundamental VM issue. And calling swapoff is just a good way
to trigger it.

If you could confirm this by calling swapoff sometime other than at
reboot time. That might help. Say by running top on the console.
