This only happens when sudo unloads the last python plugin. The reason doing so is because there are some python modules which does not support importing them again after destroying the interpreter which has imported them previously. Another solution would be to just leak the interpreters (let the kernel free up), but then there might be some python resources like open files would not get cleaned up correctly if the plugin is badly written. Tests are meant to test the scenario sudo does, so I have modified them to generally do not unlink but only a few times (~per plugin type) so it does not use 48 interpreters (one gets started on every plugin->open) and it is visible at least which type of plugin fails deinit if there is an error.
