> PySpark cancellation calls SparkEnv#destroyPythonWorker. Since there is one python worker
per process, this would seem like a sensible thing to do. Unfortunately, this method actually
destroys a python daemon, and all associated workers, which generally means that we can cause
failures in unrelated Pyspark jobs.
> The severity of this bug is limited by the fact that the Pyspark daemon is easily recreated,
so the tasks will succeed after being restarted.
