    kernel - reduce kernel stack use
    * fq_dispatcher() was eating 8K+ of kernel stack on x86-64 with a
      (512 x sizeof(pointer) * 2) sized array.  This is way too much kernel
    * Add a safety to the hz calculation in the lksleep() for hz values < 15.
      vkernels already use low hz values of ~20-ish.
