    powerd - Initial load monitor and cpu frequency adjustment daemon
    
    This daemon uses the hw.acpi.cpu.px_dom* sysctls to adjust the frequency
    for all cpus based on the system cpu load.
    
    For this initial implementation the daemon simply sets cpus to the maximum
    frequency when the 1-second load exceeds 25% of one cpu and sets the cpus
    to the minimum frequency when the 10-second load drops below 12%.
