> I'm running into a pipeline in which the decision of where to split two dependent jobs
seems to be random from run-to-run (I only noticed it b/c one of the runs causes the pipeline
to throw an NPE, and the other does not.) I'd like to investigate this and try to eliminate
any potential sources of randomness in the way that two dependent GBK operations are split.
