A question:

Are 64 bit spaces being held back by hardware: complexity, fabrication,
critical paths?  Or software (what we used to call systems software):
virtual memory operating systems that can give processes 64 bit virtual
spaces at acceptable cost?  E.g. without having to create 2 MB of
resident page tables per process, allow something lazier instead.

Anyone know which is the culprit here?
