It's maybe interesting to note that the `async` library in use here is very simple and easy to understand. Nearly every function is one or two lines. Likewise `TQueue` is extremely simple (and easy to prove correct) thanks to STM, and also generally has good performance.

While the async library is great, then everything that came before (forkIO, MVar's, etc) was already simple enough - it's only the exception handling that was missing.
