In many cases more direct control about the number of threads for a given task is required. The current way of doing so is quite involved, requiring a few lines of code where every part is important.
Like:
size_t new_active_threads = ...
size_t old_active_threads = gang->num_active_threads();
gang->set_active_threads(new_active_threads);
gang->run_task(...);
gang->set_active_threads(old_active_threads);
The proposal is to add a method that allows you to set the number of threads to use for the given task directly.
