     + Each subsystem defined by sysctl defines a list of variables
     + for that subsystem. Each name is either a node with further
     + levels defined below it, or it is a leaf of some particular
     + type given below. Each sysctl level defines a set of name/type
     + pairs to be used by sysctl(1) in manipulating the subsystem.

     + When declaring new sysctl names, please use the 0x00800000
     + flag in the type to indicate that all necessary locking will
     + be handled within the sysctl. Any sysctl defined without
     + 0x00800000 is considered legacy and will be protected by
     + both the kernel funnel and the sysctl memlock. This is not
     + optimal, so it is best to handle locking yourself.

     * These are the support HW selectors for sysctlbyname.  Parameters that are byte counts or frequencies are 64 bit numbers.
     * All other parameters are 32 bit numbers.
     *
     *   hw.memsize                - The number of bytes of physical memory in the system.
     *
     *   hw.ncpu                   - The maximum number of processors that could be available this boot.
     *                               Use this value for sizing of static per processor arrays; i.e. processor load statistics.
     *
     *   hw.activecpu              - The number of processors currently available for executing threads.
     *                               Use this number to determine the number threads to create in SMP aware applications.
     *                               This number can change when power management modes are changed.
     *
     *   hw.physicalcpu            - The number of physical processors available in the current power management mode.
     *   hw.physicalcpu_max        - The maximum number of physical processors that could be available this boot
     *
     *   hw.logicalcpu             - The number of logical processors available in the current power management mode.
     *   hw.logicalcpu_max         - The maximum number of logical processors that could be available this boot
     *
     *   hw.tbfrequency            - This gives the time base frequency used by the OS and is the basis of all timing services.
     *                               In general is is better to use mach's or higher level timing services, but this value
     *                               is needed to convert the PPC Time Base registers to real time.
     *
     *   hw.cpufrequency           - These values provide the current, min and max cpu frequency.  The min and max are for
     *   hw.cpufrequency_max       - all power management modes.  The current frequency is the max frequency in the current mode.
     *   hw.cpufrequency_min       - All frequencies are in Hz.
     *
     *   hw.busfrequency           - These values provide the current, min and max bus frequency.  The min and max are for
     *   hw.busfrequency_max       - all power management modes.  The current frequency is the max frequency in the current mode.
     *   hw.busfrequency_min       - All frequencies are in Hz.
     *
     *   hw.cputype                - These values provide the mach-o cpu type and subtype.  A complete list is in <mach/machine.h>
     *   hw.cpusubtype             - These values should be used to determine what processor family the running cpu is from so that
     *                               the best binary can be chosen, or the best dynamic code generated.  They should not be used
     *                               to determine if a given processor feature is available.
     *   hw.cputhreadtype          - This value will be present if the processor supports threads.  Like hw.cpusubtype this selector
     *                               should not be used to infer features, and only used to name the processors thread architecture.
     *                               The values are defined in <mach/machine.h>
     *
     *   hw.byteorder              - Gives the byte order of the processor.  4321 for big endian, 1234 for little.
     *
     *   hw.pagesize               - Gives the size in bytes of the pages used by the processor and VM system.
     *
     *   hw.cachelinesize          - Gives the size in bytes of the processor's cache lines.
     *                               This value should be use to control the strides of loops that use cache control instructions
     *                               like dcbz, dcbt or dcbst.
     *
     *   hw.l1dcachesize           - These values provide the size in bytes of the L1, L2 and L3 caches.  If a cache is not present
     *   hw.l1icachesize           - then the selector will return and error.
     *   hw.l2cachesize            -
     *   hw.l3cachesize            -
     *
     *   hw.packages               - Gives the number of processor packages.
     *
     * These are the selectors for optional processor features for specific processors.  Selectors that return errors are not support 
     * on the system.  Supported features will return 1 if they are recommended or 0 if they are supported but are not expected to help .
     * performance.  Future versions of these selectors may return larger values as necessary so it is best to test for non zero.
