Oh really?  CDC has several customers that have databases that exceed 2**32 
bytes.  Our file organization considers files to be virtual memory segments.
We already need pointers larger than 32 bits.  IBM's AS400 has a virtual
address space greater than 32 bits, too.  If the micro venders don't see a
need for it, they're not paying attention to what the mainframes are really
providing for their very large system customers.
