there is no difference. I think you can commit your changes, it's
improvement. Could the problem come from the matplotlib? Maybe I am using
it in an incorrect way.

I found the problem and removed it (r58598, r58599). Now it should
terminate all processes but please check. It was caused by a line of code
which actually did nothing for me but I thought it might be working for
some other version of matplotlib. I should have looked at it earlier. What
about the changes you did? Part of them like the os.kill are redundant
now, not sure about tgis.stop_subprocesses()?
