FYI: WebAssembly is effectively starting to get WebAssembly only APIs. Chrome is shipping the WebGL commit API which is designed to support spin loops in native apps (others are expected to ship it too)

Most native OpenGL apps run in a spin loop as in

    while(true) {
      update();
      render();
      glSwapBuffers();
    }

To support that model TPTB added a worker only `gl.commit` function that does effectively the same thing as `glSwapBuffers` so that native apps can keep their spin loops and don't have to refactor to be event based.

Of course if you decide to use a `gl.commit` spin loop your worker can no longer receive events (no onmesagge, no XHR, no websockets, no fetch) so you're supposed to use SharedArrayBuffers to communicate with a spin loop worker.

SharedArrayBuffers are being re-enabled once they are isolated to same domain only processes.

AFAICT this is the first browser API that is really targeted exclusively at WebAssembly. I'm guessing more will come. Not entirely sure how I feel about that but I guess it's inevitable.
