The batchSizeMapper should probably be something better than a Function<Integer,Integer>, no? All that boxing seems unnecessary... the next best candidate I can see though is IntToLongFunction. I wonder why 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. :-)
