------------------------------------
{{As JobManagerRunner::closeAsync}} runs asynchronously, The submitted jobs
have a chance to become finished if the unblock method is invoked before the
task is cancelled.
I think we can fix this by waiting the job status to become `JobStatus.RUNNING`
before we unblock operators.
