When enqueuing new jobs, respect job ID
When adding new jobs, don't add them at the end, but at aposition that fits with their job id. In this way, we canbuild operations that require fully dequeing a job an addingit later after some modifications.
Provide a function to change the priority of a queued job
There is a separation of responsibilities here. For jobs stillin the queue, it is the responsibility of the queue (scheduler),for started jobs, the job itself has to take care of it. To avoidthe job transitioning inbetween, it is temporarily dequeued during...
