    kernel - Increase machdep.cpu_idle_repeat from 4 to 750
    
    * Increase machdep.cpu_idle_repeat from 4 to 750.  It now takes longer
      before the kernel will move from HLT/MONITOR/MWAIT to ACPI-based halting.
    
    * Improves benchmark performance significantly on recent cpus without
      eating up too much extra power, but laptop tests are still pending.
    
    * Laptop users can always set it back to 4.
