I did not understand the highly synchronous, sequential, blocking behavior of the code examples. That would absolutely make the events example not work. Or is it implicit that an asynchronous operation would replace today's blocking `next()`? That `itertools.consume()` or the final `next()` would provide an async upgrade, similar to the way Unix's `select()` works? That was never explicitly mentioned...but is the only way this pattern would make larger sense / scale usefully.
