In a swapping/relocation system, the values assigned to the register pair prevent one user process from writing into the address space of another user process. However, these assignment operations are themselves privileged instructions that can only be executed in kernel mode. Is it conceivable that some operating-system processes might have the entire main memory as their address space? If this is possible, is it necessarily a bad thing? Explain.
