That's not what the question was about.

The thing is, if a browser is idle, why shouldn't it go ahead and parse
the script? That way when you want to execute it there's no sudden UI
pause as the script is parsed. I'd think this would be preferable, in
fact. So I'm opposed to any proposal that forbids browsers to
parse/compile/whatever scripts whenever they want to, assuming you can
detect when they're doing it. If you can't detect it, of course, such a
requirement is vacuous to start with.
