Why not just make:
	sysctl((void *)"kern.maxproc", 0, &buf, sizeof buf, NULL, 0);
return the value of kern.maxproc (etc).
Return EISDIR if there are extra levels, and make "kern.*" return
the list of names at the next level.

All you need then is some heuristic in sysctl(1) to work out how to
format unknown items.
