If you want, you can further optimize this by transforming sock_recv_into into an async def coroutine, and creating the fut object only when sock.recv_into(buf) fails with a BlockingError.

I don't think that's very useful, as people will mainly want to use that for large data. Right now the implementation mirrors that of sock_recv, which is easier to understand.

The doc says "The return value is the number of bytes written." but here an empty byte string is returned! I created https://bugs.python.org/issue41467 to track this bug.
