From memory: Global Atoms come from before multi-user kernels in the windows world. They are used for things like registering clipboard types - which are *not* meant to cross user boundaries. > I'm not sure what ftok has to do with whether global atoms are global > or not, however. ftok creates keys for use in IPC programs. They often need to cross user boundaries - similar in concept to the privilege separation logic in sshd these days. If we use a global atom that isn't truely global, this will break.
