Berker Peksag added the comment:

Actually, we can remove the versionchanged directive. The attached script works fine with the spawn start method in Python 3.4.

I will commit the following version:

    Ensure that all arguments to :meth:`Process.__init__` are picklable.
    Also, if you subclass :class:`~multiprocessing.Process` then make sure that
    instances will be picklable when the :meth:`Process.start
    <multiprocessing.Process.start>` method is called.
