------- Additional Comments from Pat Galizia <pgalizia at codeaurora.org>
Added comments to code explaining why we're making the check.  Also removed the
isValid() check, since that wasn't necessary.

Code seems to give a very minor performance boost to small devices, but seems
to do nothing for anything above that.	No regressions detected.
