> Currently, when submitting tasks to a thread pool, they are all commingled in a common queue. When a new task submitter shows up, they must wait in the back of the line behind all other queued tasks.
> A simple alternative to this would be round-robin scheduling, where each new consumer is assigned a unique integer id, and the schedule / thread pool internally maintains the tasks associated with the consumer in separate queues.
