A couple of years ago someone posted some assembly that would lock any
386 up solid. It didn't require kernel mode and worked on OS/2 as well as
Linux (so I doubt that it was related to a Linux bug). It was apparently
impossible to work-around this bug, thus if you want to run a multi-user
system in a hostile environment then you need something other than a 386.
