sort::test_tmp_files_deleted_on_sigint
is intermittent #3623 issueI think that
test_tmp_files_deleted_on_sigint
was failing, because sometimes the program finished before signal handling was finished, so the directory wasn't removed after all. I tested locally it was failing sometimes, after the fix I didn't see it failing.
