I've not had time to play with Python 2.7 to see how much threads help yet, but 
the scheduler needs work too.  I frequently see under 1 QPS / instance on low 
(sub 150ms) latency apps.  I may be way of the mark, but it seems like just 
getting that fixed would be a significant reduction in cost for us, and a 
better utilization of resources for Google.
