OK...why do they call it "ring" then? Does it refer to a ring like
circular data structure or something else?
Also, do ring 0 programs run faster? I guess because the CPU isn't always
second-guessing memory accesses to see if they violate segment bounds the
software has been assigned?
As for a ring 3 program being unable to currupt the kernel, I'm not sure
this is entirely correct. I discovered that a DOS program running in a DOS
box under Win 95 (and DOS boxes presumably run in ring 3) can crash the
machine with a bad memory write.
