A Very Fast Javascript thread yield (see blog posting)
View Soon
// See http://www.bluejava.com/4NS/Speed-up-your-Websites-with-a-Faster-setTimeout-using-soon
// This is a very fast "asynchronous" flow control - i.e. it yields the thread and executes later,
// but not much later. It is far faster and lighter than using setTimeout(fn,0) for yielding threads.
// Its also faster than other setImmediate shims, as it uses Mutation Observer and "mainlines" successive
// calls internally.
// WARNING: This does not yield to the browser UI loop, so by using this repeatedly
// you can starve the UI and be unresponsive to the user.
// Note: For an even faster version, see https://gist.github.com/bluejava/b3eb39911da03a740727
