And I'd argue it's a good thing because you shouldn't do that in this case, though either way you don't have that option anyway. The notion of having a supervisory process just to clean up your mess that you had every chance to clean up is just poor design. Supervisory processes are for when you can't do that and there's critical work left over, not for cleaning up random clutter you just didn't bother to try to handle at the correct time. Imagine if every program that used SQLite spawned an extra supervisory process? Now imagine if this was true for every program that needed temporary files as long as it was running? That's obviously just terrible. Your code needs to clean up after itself as much as it can, whether via RAII or otherwise, but you can't just throw out the notion of cleaning things up on shutdown (or any other point) altogether!
