When we fail to emulate an instruction for the guest, we better go in and tell it that we failed to emulate it, by throwing an illegal instruction exception. Please beware that we basically never get around to telling the guest that we failed thanks to the debugging code right above it. If user space however decides that it wants to ignore the debug, we would at least do "the right thing" afterwards.
