On CircleCI SaaS if there is queueing, all the jobs work in FIFO order (I think). If we have 10 containers and we have a job that runs tests across 8 containers in parallel, it has to wait for 8 free containers before running the job. CircleCI should either be able to run 1/8 of that job as containers become available or we should be able to set a minimum container limit to say "Ideally we would like to split across 8 but if you have a minimum of 4 available, you can run the job"
