I don't agree.  You have to be very careful with priority.  time.sleep() does 
not promise to wake up in any timely manner, and neither do the timeout 
functions.  Rather, the timeout is a way to prevent infinite wait.

In my experience (from stackless python) using priority wakeup for IO can 
result in very erratic scheduling when there is much IO going on, every IO 
trumping another.  You should stick to round robin except for very special and 
carefully analysed cases.
