but I'm interested in any answers people may have

The way other OSes handle this is by detecting any abnormal amounts of faults (sometimes it's not the fault of the hardware - eg. when a partical from the outerspace hits a core and flips the bit), then the disable the core(s).

Solaris & mainframe (z/OS) handle it this way, but you should google and find more info since I don't remember all the details.

Also, see this presentation: "Getting to know the Solaris Fault Management Architecture (FMA)": http://www.prefetch.net/presentations/SolarisFaultManagement_Presentation.pdf
