def completion(callback):
    """
    Executes a task on completion of the called action.

    Example:
        Use as::

            from gluon.tools import completion
            @completion(lambda d: logging.info(repr(d)))
            def index():
                return dict(message='hello')

    It logs the output of the function every time input is called.
    The argument of completion is executed in a new thread.
