Overview

Apple's JSContext class provides a very clean, simple sandbox for running javascript code. It turns out, though, that there are some features that node.js and web browsers implement outside of the javascript language to enable additional important functionality. One of those pieces is the setTimeout function, which the popular async module relies on in order to provide control of asynchronous code flow. As an experiment, I want to implement setTimeout in Objective-C as a block that can be attached to JSContext instances to polyfill the important functionality that it provides in the browser and in the node.js runtime.
