Would Gecko run scripts without the "ordered" property as soon as they
were ready?  Wouldn't that break the sites that are using the existing
version of labjs?

I guess I don't see the connection between the first part of Henri's

him from implementing something in the spec, and the second part of
Henri's message, where he proposes a new feature to make new code more
