Comment(by simonpj):

 Thanks for making the measurements. I assume the four runs are with
 different numbers of functions commented out?

 I have so far paid zero attention to the performance of the constraint
 solver, since "most" programs have pretty simple constraints.  Your
 program is a nice small example of something that needs better
 performance, all ready for me to profile.  Thanks.

 But other things to do first.

 Simon
