Probably isn't the correct form, but is (tangentially) relevant here. A lot of this thinking seems to have evolved because there is no good way to control what is actually eating the machine. At least in Linux - one would have to think HP-UX on that sort of kit would have something. There are moves (and patchsets) coming onstream to provide workload management/isolation in the Linux environment. It sure ain't WLM but is the start of something. As is its wont in the Linux environment, these things come from several directions at once (resource groups versus clustering versus virtual server versus ...) but seems to be progressing. How much/what gets merged into the mainline kernel is being hammered out at present.
