I would like to export the various parameters from subr_param.c
into sysctl, these nodes would include the names from the following
tunables as well as others in these files.

        TUNABLE_ULONG_FETCH("kern.maxtsiz", &maxtsiz);
        dfldsiz = DFLDSIZ;
        TUNABLE_ULONG_FETCH("kern.dfldsiz", &dfldsiz);
        maxdsiz = MAXDSIZ;
        TUNABLE_ULONG_FETCH("kern.maxdsiz", &maxdsiz);
        dflssiz = DFLSSIZ;
        TUNABLE_ULONG_FETCH("kern.dflssiz", &dflssiz);
        maxssiz = MAXSSIZ;
        TUNABLE_ULONG_FETCH("kern.maxssiz", &maxssiz);
        sgrowsiz = SGROWSIZ;
        TUNABLE_ULONG_FETCH("kern.sgrowsiz", &sgrowsiz);

any objections?

I don't see any obvious way to get at these values on a running
