>> Only a few tasks use this infrastructure and most tasks run the setup code in the constructor or before the task is constructed. There is no place where we construct a FlexibleGangTask task, change the number of active workers, and then start the task. The tasks are always started near the construction site. So, I propose that we get rid of AbstractGangTask::set_for_termination to shrink the AbstractGangTask API.
