The V8 sandbox doesn't just protect against JIT issues, it also protects against logical issues in the runtime and object model.

Not exactly. It's the nature of a sandbox that it doesn't remove bugs, it only reduces their blast radius. The Truffle architecture actually removes bugs by changing how you write the language VM to begin with.

		I said it "protects" against bugs, not that it "removes" them. The Truffle architecture removes mismatches between JIT and interpreted code (when it doesn't have bugs itself, which is not guaranteed either), but it doesn't remove runtime or object model logic errors that affect both.
