That's correct.

Normally systematic freeing of resources is one of the best ways
to prevent memory leaks in long running programs, so it can't be
too bad to free/delete all malloc-ed/new-ed chunks upon exit.

But here, the opposite may be better: there should be a faster
way to exit, bypassing all manual and automatic cleaners. But that's
up to every single program and not OS'es business.

Thanks again for all the insight.
