start_cycle t ~max_num_jobs_per_priority enables subsequent calls of run_jobs to run up to max_num_jobs_per_priority jobs of each priority level.

val run_jobs : t -> (unit, exn * string) Core_kernel.Std._result

run_jobs t removes jobs from t one at a time and runs them, stopping as soon as an unhandled exception is raised, or when no more jobs can be run at any priority, as per ~max_num_jobs_per_priority.
