    @class IO::Interface
    
    Implements the asynchronous interface to the IO subsystem. This will
    run a minimal Nebula3 runtime with an IO subsystem in an extra thread.
    Communication with the IO::Interface happens by sending messages to
    the Interface object. Messages are guaranteed to be handled sequentially 
    in FIFO order (there's exactly one handler thread which handles all 
    messages).
