Prerendering in flight is similar to prerendering in Fizz. Instead of receiving a result (the stream) immediately a promise is returned which resolves to the stream when the prerender is complete. The promise will reject if the flight render fatally errors otherwise it will resolve when the render is completed or is aborted.
