I'm using #40, the Intel Mac version. I'm just in the process of  
downloading the new binaries.

Is there any way to get more useful profiling information about the  
constraint system? I don't mean to be rude, but being told that 50%  
of my time is being used in the core propagator is like telling me  
that 50% of the time in a C program is spent executing statements.  
Which ones?
