It's not just a matter of degree. If the UA follows the spec, authors can
(fairly easily) write code that's race free. Darin's proposing to make it so
they can't --- at least, not without external help like shared workers or
Web Storage, in which case I wonder why one would use LocalStorage at all.
(OK, I suppose one could rely on key/value atomicity and implement Lamport's
bakery algorithm on LocalStorage alone. I hope to never see that...)

That is a good point. You do have the option of doing better than IE, though
"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
