All generators are asynchronous; when called they return a generator object instead of running to completion. The @gen.coroutine decorator communicates with the generator via the yield decorator receives a Future from the generator, waits (without blocking) for that Future to complete, then “unwraps” the Future and sends the result back into the generator as the result of the yield expression
