It's awkward to await on a `Stream.async_done()` for the purpose of enqueuing something new onto the stream, because there is no way to tell which stream finished from the completed future - this forces the user to maintain a mapping between futures and streams. This commit makes the result of the future be the stream on which operations completed, so that the user can obtain the stream from the completed future.

This is great, thank you @gmarkall, really useful for streams with non-uniform workloads, as @stuartarchibald said, such as the satellite data feeds I work with. |
