Not really. But a manager also lets you share lists, dicts,
namespaces, or other registered types. Note that a proxy isn't thread
safe, so it should be used by only a single thread, or with a lock.

You could have another function that does that, or subclass
multiprocessing.queues.Queue to override its `put` method.
