The batchSizeMapper should probably be something better than a

we didn't do an IntToIntFunction in JSR 335. Or maybe the stream itself
should be somehow made aware of the optimum batch size. What's the use
case for changing the batch size as you iterate? Is the traversal
*that* expensive?
IntToIntFunction => IntUnaryOperator.
Ah that's the one! You know I think that this is more than once that I
looked for, and didn't find, that interface. Some kind of mental blind
spot I guess. :-)
