   If I'm not mistaken, this was done on the iAPX432, using a capability-
based addressing scheme.  Dimmed the lights.  You could probably construct
such an environment on the 80286, but no one does, probably for efficiency
reasons.

   You're probably better off with a language that compiles checks into
the code, and an option to turn off those checks once you're confident
(?!) of the program.  With a capability-based architecture, you pay the
price all the time, whether you want to or not.
