On 2.6.10-rc3 with Con's patch, when I run the memory eater, there is a high
kswapd CPU load for about 10 seconds, then things are OK. The screen never
freezes at that time or at any other moment.

When I add vm-pageout-throttling.patch from -mm, the CPU load in the beginning
is somewhat less constant but remains there.

While it would be nice to fix the high CPU load, the system is usable as it
