Comment (by zzzeek):

 Running this against 0.8, only one of the aaa_profiling tests falls out of
 range here.  Here's a summary of most of the ORM related profiling tests.
 The orm_2010.py script has the best savings as it works with a large
 number of objects.  Overall these savings aren't too dramatic.
