x86-64 performs 64-bit *calculations* natively.  There are only 40
memory address lines (or there were in Hammer), giving a
directly-addressable range of 1TB.  This was touted as a great thing,
because it meant you could memmap your entire hard disk.  Of course,
now you can get a 1TB hard disk for $200 on Newegg.
