I think this is still an issue when the system is rebooted, everything is tmp is deleted :/

Yeah, that definitely happens. I don't want to be generating a lot of persistent files in the default case. But maybe we can push the temp files into an alternative location. I was originally thinking of adding an argument but the python implementation already has an environment variable (apparently 3 actually) for this case that you could use.

https://docs.python.org/3/library/tempfile.html#tempfile.mkstemp

The default directory is chosen from a platform-dependent list, but the user of the application can control the directory location by setting the TMPDIR, TEMP or TMP environment variables.
