   I don't know about CDC, but the AS/400 uses what is called Single Level
   Storage, that is, all memory and disk are in one humongous address space.

   Many people do require more than 2**32 bytes of disk farm, but very few
   people are using 2**32 bytes of memory space--so in a more typical system
   the need for (pointers) more than 32 bits is rather uncommon %
