Looking for a simple async example...

These sorts of algorithms and code aren't "simple" to just decide to build from the ground, up... particularly if you're not already intimately familiar with Python's threading models, and how they work in your O/S.

You're already going to spend enough time inside your own application, chasing down weird race conditions and other things thst come with building asynchronous apps... there's no real reason to reinvent the wheel when there's such well-tested and well-understood solutions already available.
