The later 2.3.99-pre* kernels have serious virtual memory management
problems on many machines; the visible effect is kswapd hogging massive
amounts of CPU time on even reasonable levels of I/O. I found them
unusable for any length of time on my machine. Looks like it should be
fixed soon, though ...

I've heard some rumours that 2.2.15 *may* have similar problems, but I
can't offer much more than innuendo. I think we'd need more than rumour
to roll it back out of the test cycle.
