* A Capped_supervisor is a process supervisor which which will limit the * number of active processes to some specified capacity. Specifically, it * allows the definition of a job runner which jobs can be dispatched to, * where dispatched jobs are added to a queue and a pool a processes work * off the queue, with at max job_capacity jobs.

This module provides a functor for instantiating async supervisors which is * capable of monitoring and dispatching work to a single worker. The module * allows synchronous checking of the worker's state (is it processing work * or not), and prevents parallel dispatching of work to that worker.
