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)":
