----------

The function to call.

The positional arguments.
kwargs : dict, optional
The keyword arguments.
Returns
-------
future : ApplyAsyncResult
The result of calling the function boxed in a future-like api.
Notes
-----
This calls the function eagerly but wraps it so that ``SequentialPool``
can be used where a :class:`multiprocessing.Pool` or
:class:`gevent.pool.Pool` would be used.
