as far as I'm aware, on OSX the only time that the values actually get
set is the *first time*, after bootup, that you run, say:
sysctl -w kern.sysv.shmmax=8388608
So if you have a sysctl.conf, it will have already set them. The line
you've commented out can't change them because they've already been set.
