Asyncore scheduler - delayed or recurring tasks for asyncore

Question

Python

Colleagues, I want to share my little craft, maybe someone will be interested.
Some time ago I wrote a program to compare data from 2 DDE servers based on asyncore.

Empirically, I realized that in order for the connection between the server and the client
(the server is a proprietary closed program) not to break,
I need to send "> Ping \r\n" to the server once in a while.

After a lot of searching, I never found a simple solution and decided to try to write it myself.

Here's what happened: github.com/stavinsky/asyncore_scheduler

Actually I'm writing in questions because I don't consider myself a programmer and I'm not sure that someone will be
interested in seeing this in the form of an article, but at the same time I want to get feedback.

So if anyone is interested: look, use.
I hope for fair feedback that will help make the code better.

PS I know that twisted is better and everything is already out of the box.
