Streaming Consideration

Let's address the original problem: why we need streaming?

When an action takes too much time, say, when it has to do an oauth validation with google. In usual applications the client may not have any of the result page until the action completes. One solution is to use streaming, and send chunks eagerly. But template rendering in Rails is not friendly to streaming, then I came to the idea of the first streaming design, and let Fiber.yield trigger the render buffer flushing.

But it is not very useful indeed, and makes the View class too complex. One can usually use front-end techniques to do the same job: render a page with quick data at hand, and ajax load the rest that takes time.
