AI Summary: Implement thread safety for the `winpoll` library's `wsapoll` function, ensuring that concurrent calls from multiple threads are prevented, mirroring the behavior of CPython and PyPy's `select.poll` implementations. This involves adding synchronization mechanisms (e.g., locks) to protect shared resources within the `wsapoll` object.

AI Summary: Add docstrings to the `winpoll` Python library, which provides a pure Python implementation of `select.poll` for Windows using `ctypes.windll.Ws2_32`. This involves documenting the module, classes, functions, and methods to clearly explain their purpose, parameters, and return values.
