Problem: resources are not cleaned up properly when the message websocket handler is cancelled. This is because aiohttp appears to raise a CancellationError. Solution: use `asyncio.shield()` on the whole handler. Added a decorator to avoid splitting the implementation of shielded functions. Protected the POST /messages endpoint as well as it also uses a message queue. fix
