The result is good but the patch isn't the way I chose to implement
this.  I appreciate the idea, though.  The performance improvement
is amazing.

Thanks for the patch/idea.

P.S.  I really do appreciate the effort that you put into this but, had
it been accepted, it would have required some reformatting since you
used a different indentation style from the rest of the code.  I hope
that you'll consider keeping your changes formatted like the surrounded
code.  It will make patch adoption easier.
