tsolanto,
The AFCI breakers are designed to ignore the type of situation you describe, just as it would ignore the internal arc in a switch that controlled a load as it was turned on and off. It is supposed to see these as "good arcs" and not bad ones.
Aside from that, there are many that agree with your thoughts about not including the smokes on the AFCI circuit.
I'm thinking I heard that Canada does not permit it. Electric-Ed; can you confirm that?
