D106720 introduced features that did not work properly as we could add new queries after a fixpoint was reached and which could not be answered by the information gathered up to the fixpoint alone. As an alternative to D110078, which forced eager computation where we want to continue to be lazy, this patch fixes the problem. QueryAAs are AAs that allow lazy queries during their lifetime. They are never fixed if they have no outstanding dependences and always run as part of the updates in an iteration. To determine if we are done, all query AAs are asked if they received new queries, if not, we only need to consider updated AAs, as before. If new queries are present we go for another iteration.
