60 this one. Unlike -dependencies, these are considered non-critical.

66 When it is called, all the verifier stages listed in -requiredStages will
67 have run. At this point, it is possible to access them using the
68 verifier's -stageWithName: method in order to query them about results.
69 Stages whose dependencies have all run will be released, so the result of
70 calling -stageWithName: with a name not in -requiredStages is undefined.
71
72 shouldRun can be overridden to avoid running at all (without anything
73 being logged). For dependency resolution purposes, returning NO from
74 shouldRun counts as running; that is, it will stop this verifier stage
75 from running but will not stop dependencies from running.
