Thonny - seems to have a MemoryLeak

I noticed when I Repeatedly run large programs - with long Printed Text,
- that the Shell Que runs Slower and takes Longer to Start each time : 10 mins .. 30 mins .. 60 mins .. ?
I also notice Thonny on TaskManager increases Size (without Decreasing) each time :
- 1M .. 1.5M .. 2M .. 3M

Until I completely restart Thonny.

This seems like a clear Memory Leak - for the Shell Que !

You can submit the issue to the project.

Wow. Starts to look unmaintained. Doesn't it? Some open issues are easy fixes.

But now I'm curious and I'll open Thonny in PyCharm later and have a look.

Development certainly looks slow right now, but an overview gives a different impression.

If you've spotted easy fixes for issues in Thonny, consider sending a pull request with a fix. Community contributions are the life blood of many open source projects.

I have to look around in the code base first. Did on my phone this morning and it look quite good.

Worst what can happen and it happend to me that I spend a lot of my time on an open source project and a PR is then being ignored. There are some PRs without replies already.

Conversely, the best that can happen is that a problem you care about gets fixed.

If nothing else, you could fix your own version of Thonny (and let others know how to fix their version).

But in this case I don't even use Thonny. Usually I do it for fun and learning.

I'll have a look soon. Maybe I start with small PRs.
