No he wasn't.  Remember the "page size" issue?  Run them at 2mb and the TLB
issue changes a _lot_ as I mentioned.  Other processors have a much bigger TLB
to boot.

But latency is too-well defined.  Time to do _one_ read from memory.  Not "time
to read two or four page tables plus the time to read the actual data."
