When we add more of these features, I think we will need a way to acquire
multiple locks simultaneously before running a callback. (So if we had
localStorage.runTransaction(function(storage) { ... }) and
otherLockingThing.runTransaction(function(thing) { ... }), we could also
have, for example, window.runTransaction(localStorage, otherLockingThing,
function(storage, thing) { ... }).) So it may be worth thinking about what
that API should be and what we will need to add to each feature spec to
support it.

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
