Context

Our async IO currently uses non-blocking sockets to match as closely as possible to the synchronous API. We should investigate using asyncio transports/protocols instead, which are asyncio's fastest interface for network IO.

Definition of done

Investigate asyncio transports/protocols and migrate our asynchronous code to use them, if compatible with our use case.

Pitfalls

Using a different networking implementation for the asynchronous API will require additional complexity in our synchronization system, as the two APIs will no longer share a common network layer.
