I've updated current a few times since you added your changes, and for some
reason, those new sysctl's never showed up. I have them in my sysctl.conf,
and every time I boot it tells me they're invalid, and I don't see the new
names (execmin,execmax,etc) in sysctl -a, either. Am I doing something
wrong?
