Checking beyond the shown context, I see that it doesn't bother with removal since the next test removes the directory as a preparatory step. Even before the addition of test_when_finished() to restore write permission, the subsequent test's removal of the directory worked because this is test is only run when POSIXPERM is met, and POSIX allows for such an operation. Okay, looks good.
