   Sorry if my English was confusing.   
      
   I don't want to use paging. I don't want page tables.   
      
   I will do a simple malloc of 8 GB, unprivileged. That will   
   get me a 4 GB boundary. Someone in IBM-MAIN mentioned   
   that they did the same thing and called them "continents".   
      
   Then I can run a PDOS-generic application and it can have a full   
   4 GB.   
      
   And call another PDOS-generic application which gets another 4 GB   
   (if I malloc 12 GB initially instead of 8 GB).
