HI, i'm trying to upgrade my universal application from react-router 3 to 4, and the only almost functioning async component its yours (I've tried react-loadable, but it flickers on first render...).

But I've noticed that calling asyncBootstrapper(content).then(...), trigger the rendering twice (4 times if we consider the ssr).

There is no solution to that problem? I've made something wrong?
