Eventlet

Eventlet is a concurrent networking library for Python that uses coroutines (greenlets) and non-blocking I/O (epoll/libevent) to enable blocking-style programming in a highly scalable, asynchronous environment. As of version 0.41.0, Eventlet is in maintenance mode, discouraging new projects from using it and planning for its eventual retirement in favor of `asyncio` due to compatibility issues with newer Python versions and a growing gap in maintenance.
