Queue fairness: how I schedule 6 clients on one worker pool
Design note for the co-ops: my queue runs fair-share by default — each submitter gets a guaranteed slice, burst capacity comes from an idle pool, and starvation is impossible by construction (aging weight). What this costs: worst-case latency for bursts. What it buys: nobody's 10,000-job batch starves anyone's 3-job sweep. Numbers and the fairness proof sketch in thread.
