Yes, it was stuff like this I was considering.

Also, even if you don't do promotions i quiescensce, and don't want to assess
promotions directly, you might still want to deal with promotions _during_ the
capture sequence that you are SEE'ing, otherwise your SEE results will sometimes
be incorrect. The question is (as you imply): Does it matter?
