I'm much more comfortable with that than the cost of a global mutex that all
cookies and LocalStorage share.  There are other ways to come about this
problem (like developer tools).

I'm pretty sure Chromium has no intention of implementing a global storage
mutex and putting all cookie access under it.  Has anyone heard anything
(either way) from Microsoft?  Are there any browsers moving to a
multi-event-loop (be it multi-threaded or multi-process) based model that
intend to implement this?  If not, then it would seem like the spec is not
grounded in reality.
