خطوة بخطوة

1. Create an ArrayBlockingQueue<OrderEvent>(50) and a producer emitting events quickly.
2. Start 3 consumers on a fixed pool that "process" each event in 50 ms.
3. Log queue size and producer wait time; show the producer slowing down once the queue fills.
4. Planned mistake: swap in an unbounded LinkedBlockingQueue and watch the queue and heap grow without limit. Fix: restore a bound.
5. Add a poison pill per consumer for clean shutdown; verify produced equals consumed.
