Motivation
See here for a longer motivation:
rust-lang/futures-rs#1727
The TLDR is that I think a "split_mut" method on types implementing traits like
AsyncRead
could open up the possibility of the AsyncRead/AsyncWrite trait methods returning "normal-ish" futures, and eventually allow the methods on these traits to be implemented using async functionsNote: this is more useful than it might appear, because the Pin API allows the ownership of a TcpStream, and non-static borrows of that TcpStream to be bundled into a future without any lifetime bounds of its own.
