   And the OS could be configured to have a couple of flags.   
   One is to identify the huge pointer segment manipulation   
   algorithm, so 8086. Another is to say whether the OS   
   (via user configuration) insists that the app use the   
   OS-supplied routine.   
      
   So the app is free to use its more efficient algorithm,   
   but the OS has the ability to regain control if there is   
   something unusual about this 8086 that prevents   
   normal manipulation. I can't think of what that might   
   be, but that's why the flag might exist.   
      
   So long as the app obeys the rules, all is fine.   
      
   And again, I only care about apps that obey the rules.
