Fie on that nonsense. What y'need is 33bits. 32 for a decent size
integer (who*needs* 64 bit values, anyway) and one bit for a tag.
Then you need an asynchronous ARM-like architecture with the TLC
(sorta WCS) and floating pint hardware connected to fullspeed mram so
that there is no need for data cache. Then you have a few thousand of
those in a single machine. Easy. Now gimme One Billion Euros to
implement it.
