def __exit__(self, exc_type: type, exc_val: Exception, exc_tb: Any) -> bool:
        """
        Exit the context manager.

        The default behavior of a `futures.Executor` is to shutdown and wait.  `ThreadExecutor`
        does whatever is specified in the `on_exit` parameter to `__init__`

        Args:
            exc_type, exc_val, exc_tb:  the exception data for any exception raised in the managed context, or None,
              if no exception was raised.

        Returns:
            a bool indicating whether or not the function handled the exception, if one was raised in the managed
            context.  If False, and there was an exception, the python runtime will raise the exception.
        Raises:  None
        Required Tests:  None
