isn't this loop a no-op, as the return always ends it on the first loop?

This continues the poll rx on Err(err) instead of returning Pending, and ensures that the underlying stream is completely drained or returns a valid element.

streams only register the waker if they're pending
Returning "pending" when the underlying stream is still ready does not ensure that the rt will poll again.
