  MFp4: //depot/projects/usb@155842
  
          Reduce the number of callback processes to 4 per
          USB controller. There are two rough categories:
          1) Giant locked USB transfers.
          2) Non-Giant locked USB transfers.
          On a real system with many USB devices plugged in the
          number of processes reported by "ps auxw | grep USBPROC"
          was reduced from 40 to 18.
