--------------------------------------

Is this a dupe of BEAM-65?

> BoundedSource has splitAtFraction and related code to enable large work items to be split
dynamically and moved to other workers.
> UnboundedSource does not have this support -- instead, runners are expected to allocate
many splits initially and rebalance those between workers.
> We should add dynamic work rebalancing to UnboundedSource. This will almost certainly
be done by checkpointing the source, and then the dynamically produced splits will both inherit
the checkpoint (or a split-adapted version of it).
