> C presents a simple "big array of bytes" memory model that totally abstracts all that complexity.
I don't understand what you mean by this. Machine code itself abstracts away the underlying hierarchical memory structure. Sure, some machine language might have instructions to manipulate the cache, but those are easily invoked from C, using either inline assembly or __builtin functions.
