Title:  Results class optimization

Description: We have a large query implemented via a SQL Method. We've
been messing with it to get the most speed out of it, and noticed a
large hit in the __init__() method on the Results class. We found that
with this simple tweak (see included patch) we got around a 180% speed
up. Not a ton, but pretty good for changing 3 lines of code.
