It is not free to copy data from the leader to the worker. I don't
think we should just adopt a policy of copying everything anyone
thinks of, because then most of the time we'll be copying a bunch of
stuff that really isn't needed.
My gut reaction is to think that this is way too marginal to be worth
making parallel-safe, but it is also possible that I just don't know
enough to understand its true value.
