Someone asked why the Mac OS doesn't use memory protection etc.  Part of the
problem lies in the fact that although the 68000 series has both a supervisor
and a user mode, the Mac does not reserve supervisor instruction for OS only
use.  Current Mac programs run in the supervisor state, always.  This is weird
but this is life.
