People with less than about 144MB of memory will have their pagetable area reduced in size, in some cases by a lot. I'm not going to apply this until I see some favorable test results. I'll try to do some testing myself, but people with smaller-memory machines need to give this a spin on their workloads and provide feedback. -- Keith M Wesolowski
