The deduction messages are happening because the side-effect forcing
logic fires whenever a symbol is set. It has no way of knowing
whether or not the forced symbol will occur later in the config being read.

I think it's because of the different timing of menu visits (forcing computation
of choice-menu defaults at different times). I'm going to run some experiments
to see if I can pin this down.
