The new thing in this patch is the -g option which enables testing of newly created (other than default) groups. The default is not changed. In practice "all" vs. "workers" do not matter much in our current test apps, since ctrl threads do not call schedule(). I'm thinking that those automatic groups should be configurable, so that e.g. "all" and "ctrl" maybe disabled if not used. Those configs would go to new scheduler global config params (with other things). Anyway, not a topic of this patch set. -Petri
