What is the effect of a judicially determined good faith settlement on a pending action or claim?

"[E]mployment of a distinct procedure to adjudicate the effect of a judicially determined good faith settlement upon a pending action or claim not only is procedurally necessary but also serves an important salutary function: it focuses the court's attention distinctly upon two completely different substantive questions--whether the settlement was in good faith and whether the claim sought to be dismissed is of such a nature as to be barred by a good faith settlement." (Shane v. Superior Court, supra, 160 Cal.App.3d 1237, 1246, 207 Cal.Rptr. 210.) The need for such particularized adjudication becomes apparent in this case.
