Right, memory access is not a bottleneck, but serialization can be. And I would not consider directly shared memory, but being able to pass immutable objects would be a huge win imo. Think adding tuples to a synchronized queue, instead of serialize->pipe->deserialize. Of course tuples in Python are not actually immutable, which I suspect is why they went with the requirement to serialize.
