    This is useful for running 'background helper' type concurrent processes.

    NOTE: It is strongly discouraged to pass Channel objects outside of a recipe
    module. Access to the channel should be mediated via
    a class/contextmanager/function which you return to the caller, and the
    caller can call in a makes-sense-for-your-moudle's-API way.

    See ./tests/background_helper.py for an example of how to use a Channel
    correctly.

    It is VERY RARE to need to use a Channel. You should avoid using this unless
    you carefully consider and avoid the possibility of introducing deadlocks.

    Channels will raise ValueError if used with @@@annotation@@@ mode.
