Comment(by CoreyOConnor):

 Yes, the successive runs are with increasing number of functions un-
 commented out.

 I understand, and agree, that other things should come before performance.
 Still, as I can't help out much with correctness I am going to start
 looking into optimizations. Perhaps there are some easy and safe
 optimizations I can contribute.
