Yeah, I do not think we are expecting to fast track these two series
through 'next' to 'master' before 2.3 final, so I think it would be
better to use this patch _only_ to see if the final shape of the
code this patch represents makes sense, so that we can expedite the
final submission in the next development cycle, at which time we
will have a chance to refresh 'next', hence a chance to clean-up
atomic-push series in place.

Thanks.

Is this hashcpy() still necessary?
