Speaking of Really Bad Ideas: V8 flags aren't designed to be toggled arbitrarily at runtime. I wouldn't be surprised if lots of stuff started breaking when you mess with flags. (If I were to design an embedder, I wouldn't even provide a "v8.setFlagsFromString()" interface, because having one just begs for people to shoot themselves in their feet.)
