This was the original implementation, but it turned out to be less  
effective for several reasons:
1. Groups that change frequently result in too many system calls for  
managing the group (think of users joining and leaving a live  
broadcast);
2. Allowing the caller to maintain the group is more flexible than  
having the kernel responsible for it;
3. No support for per-call per-recipient data.

Point 3 is useful in some scenarios, such as multiplayer online games,  
where the bulk of the data is shared, but each player also receives a  
small chunk of dedicated information.
