Umm, this is not a good way to do it as it is dependent on kernel size
adjustments. It would be far better to use the sysctl kern.usrstack
instead, and perhaps falling back to the predefined USRSTACK if for some
reason the variable isn't available.
It's even got a numeric OID (KERN_USRSTACK) so it doesn't incur the
expense of doing a name translation.
