Added commit 5e71279: kept the GitHub Pages workflow content at docs/ci/docs-pages.workflow.yml as a ready-to-move template, since this token cannot write .github/workflows/*. |

SimpleConnectionPool 的实现不是线程安全的。多个线程并发调用 acquire 时，对 self._created 的检查和修改存在竞争条件，可能导致创建的连接数超出 max_size。连接池通常在多线程环境中使用，因此线程安全至关重要。建议引入 threading.Lock 来保护共享资源的访问，例如在 __init__ 中初始化锁，并在 acquire 方法中对检查和修改 self._created 的代码块加锁。

为了确保数据库连接和游标在任何情况下（包括异常发生时）都能被正确关闭，建议使用 with 语句来管理 Connection 和 Cursor 对象。这可以使代码更简洁、更健壮。
