You are right, that warning is exactly what is causing the issues.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1730664352

I would have thought that the global (or module level here) variable/function aquire should have at least one reference until after the deletion of the object.
Is that a bug in pythons garbage collection?

Or does the garbage collection already start when calling `del` and does not wait for the completion of the `__del__` method?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1730664352
