Aren't there situations where network traffic occurs without significant 
"process" involvement?

I remember a couple of years back, when my XO-1 (if so enabled) would 
suspend while I had a 100 MB ethernet transfer ongoing - I needed to 
periodically press something on the keyboard to keep that XO-1 awake.
