Pipeline

A ventilator sends jobs to multiple worker processes, which send the results to a sink.

Channels:

• ventilator -> worker: jobs for the workers
• ventilator -> sink: IDs of jobs sent to workers, so sink knows if all jobs have completed
• worker -> sink: results
• sink -> worker: sink sends shutdown command, when finished
