SVN rev 187174 on 2009-01-13 19:03:23Z by thompsa
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.
