Guys, notice what I'm talking about. The performance hit of Ring 3 protection is about 20%, C++ can never ever run without Ring 3 protection, so no, C++ does NOT have 0 overhead. Javascript could, as it's safe. There's a lot of scientific research going on, because people expect that placing a VM in Ring 0 might mean that VM languages would get a 20% boost in speed, potentially making them even faster than compiled languages. This is not a claim I make, this is scientific and we'll see the results really soon, though a consumer product might be years away.
