> This primarily means calling the {{BoundedSource#splitAtFraction}} API during the evaluation
of a BoundedReadEvaluatorFactory - this can return the work via addUnprocessedElements. 
> At a later point, the {{MonitorRunnable}} within {{ExecutorServiceParallelExecutor}}
can examine currently evaluating work and invoke a {{TransformExecutor#split}} method, which
can return to the runner some amount of input, which can be scheduled to use more of the available
threads.
