I don't think the tradeoffs between segments and a flat address space are
the same now for >32 bit machines than they were for >16 bit machines.

In the past decade, memory cost has dropped by about 2^8.  The 32 bit
address space that some find too small costs 2^8 times as much to fill as
the 16 bit address space did 12 years ago.
