* In some cases, we can first call sigaction()/signal(), then *not* pledge sigaction. * In other cases, we pledge sigaction at first, call sigaction()/signal() second, then pledge again, this time without sigaction. * In yet other cases, we keep the sigaction pledge. I suppose these could all be migrated to drop it or not pledge it at all, if somebody is interested in doing that.
