• [x] I have added an entry to CHANGELOG.md

Summary of changes

Original patch by Leonardo Pereira Santos (see PR https://github.com/cs01/pygdbmi/pull/55); updated by Marco Barisione.

This is the description for the original PR:

Removed the make_non_blocking function. Refactored the _get_responses_windows method to use separate threads and queues to make reading non-blocking. solution based on this StackOverflow answer

Tests don't pass on Unix and I'm reluctant to modify the code as I cannot test it on Windows so I will let this here in case anybody can help.

Fixes #54

Test plan

Tested by running

nox -s tests

CURRENTLY FAILING ON UNIX

[cs01]

If anyone else ends up taking this on, GitHub actions support windows, so adding a windows CI test would give good confidence in the change and ensure it doesn’t break in the future.
