With new attacks like TLBleed etc. it is becoming increasingly clear that

evolution seems to have been to accommodate C's simple memory model.
That's the strangest thing to see: *why do people think the point he's making is
in any way controversial*, because it's so obvious.

'giant PDP-11s' for a long time and now he's stolen (obviously not stolen:
independently come up with) my term, pretty much.)
