The trick is to make sure the API works for all that, then make it for a
subset of useful machines. I.e., if you're doing persistant addresses,
don't use 32 (or 64) bits. If you're doing files, make sure you define
the semantics for networked files. If you're doing tasking, make sure
you can specify what you need to to make NUMA work.
