Description
pyinstaller has a hook to change the matplotlib config environment variable to a random directory every time the program starts: pyi_rth_mplconfig.py
This hook is a hack to avoid some other problem which I can't quite figure out but it was added in
https://github.com/pyinstaller/pyinstaller/commit/213bfc3923055cfc18ba7248db5124dbfccea3f9
in artisan, we got a bug report about startup slowness:
https://github.com/artisan-roaster-scope/artisan/issues/178
I've tested pyinstaller+artisan without pyi_rth_mplconfig.py and nothing breaks, so I'm not sure if this hack is still needed.

Research direction
Start by reading pyi_rth_mplconfig.py and the linked commit 213bfc3923055cfc18ba7248db5124dbfccea3f to understand why the environment variable is changed. Review the Artisan issue 178 and compare behavior with and without the hook; done means resolving whether the hook is still needed without reintroducing the reported problem.
