Just to round out this discussion - if QGIS does crash, then these
files are still likely to be cleaned up by the operating system
itself. E.g. on linux they'll be cleaned out at next reboot.

I know that there is a setting for default output files (defaults on Windows to C:\Users\username\AppData\Roaming\QGIS\QGIS3\profiles\profilename\processing\outputs - but is this really the same location where also temporary files that are needed during the processing are stored?
