You are mistaken. First, since rlim_max==RLIM_INFINITY the limit is
not enforced (unless Apple totally screwed up the setrlimit() API).
Second, rlim_cur was 256 because YOUR patch changed it. Third, you
could test your concern by setting a really low rlim_cur and seeing
if it is enforced while rlim_max==RLIM_INFINITY.
