> Today there is nothing in the system which keeps track of the processes in a group, process groups don't really exist at all. A "process group" is those processes which have the same group leader. The group leader has no information about which processes have it as group leader. You can make any process a group leader by setting it as group leader.
> Process groups were explicitly added in such a way as NOT to impose any structure or hierarchy on processes, process space is flat.
That's right. I personally understand them as "ephemeral" notions,
just like you defined. That's why I don't do anything if a group
leader dies. It's a duty of individual process to decide what to do
