Can you explain the principle of the Event Pool system?

Event Pool is a structure or mechanism used for managing and processing events within a system. It typically represents a queue or a set of events awaiting processing. The working principle is as follows:

1. Events (such as user actions, system signals) are placed into the Event Pool.
2. A dedicated handler or event loop sequentially retrieves events from the pool.
3. Each event is processed by the corresponding handler or function.

This approach allows for efficient management of asynchronous events, simplifies architecture, and improves system responsiveness. In Python, a similar mechanism is implemented in asyncio using an event loop.
