Here we are making assumptions about how people will use routines that don't
actually exist yet. If you were to substitute "new Date().getTime()" for
"self.getAllCookies()" in the code above, I think we'd all agree that the
user expectation is faulty - is it not feasible to state that, just like
Date().getTime(),. getAllCookies() returns a snapshot of a mutable value?

I'm OK with making setCookie() asynchronous, because I think there may be a
valid point that you don't want new worker code to suddenly break existing
JS code that expects document.cookies to remain immutable across a single
block of execution. But I don't see that argument extending to

I'm looking into this now, actually :) - I'll let you know what I find out.
