Currently we have exact 4 jobs to be run with at most 4 parallel
processes. This sounds as if we're testing only one special case,
but in reality we want to have any number of tasks be processed
successfully, so test:
* more tasks than max jobs (implying slots get reused)
* equal number of jobs and max jobs
* less tasks than max jobs (implying there are unused slots)
