Currently, the default pickle protocol is used to return worker results in a multiprocessing pool. The highest protocol should be used because backwards compatibility is not an issue. |

As described in issue23403, it is possible for independent processes to communicate to one another through multiprocessing. Thus changing the default triggers complications and is arguably much less interesting than having control over what protocol (or mechanism) is to be used for pickling. |

Agreed with Davin. |
