Пакет python3-module-eventlet: Информация

Eventlet is a concurrent networking library for Python that allows you
to change how you run your code, not how you write it.

It uses epoll or libevent for highly scalable non-blocking I/O.
Coroutines ensure that the developer uses a blocking style of
programming that is similar to threading, but provide the benefits of
non-blocking I/O. The event dispatch is implicit, which means you can
easily use Eventlet from the Python interpreter, or as a small part of a
larger application.
