I am not saying it isn't legitimate. But the most common case is the main thread waiting for its threads or calling exit which would tear the whole group down. Is there any easy way to achieve this other than tkill to group leader? Calling exit(3) from the leader performs group exit IIRC. I am not arguing this is non-issue. And it certainly is a problem once somebody wants to be nasty... I was more interested how often this really happens for sane workloads. -- Michal Hocko SUSE Labs
