One thought, the 8088 and subsequent processors of that bastardized family
have all had one little thing that none of the others (6502, Z80, etc) have
had and that's some kind of instruction that CANNOT under ANY circumstances be
preempted.  Now, I am not dead sure of the 8088 but the children of it have
had this instruction.  Now you can't still say that this legitimizes the idea
of multiprocessing (or any other word prefixed by "multi") but it did allow
you to do more than you can without it.

But as has been shown many times you ain't close without hardware level memory
management.
