@Terry: Robert is usually called Ronald :-)

That’s because I only noticed the PR after commit: The PR was merged within an hour of creating the BPO issue.

The principle was that bigger changes needed to go in as early as possible in the release cycle so that we could thoroughly exercise it (something that almost never happens while something is in the PR stage).  It would be great if the same came happen here.  IIRC, shared memory has long been the holy grail for multiprocessing, helping to mitigate its principle disadvantage (the cost of moving data between processes).  It's something we really want.

But with dataclasses there was public discussion on the API.  This is a new API with no documentation in a part of the library that is known to be complex in nature.
