A desktop system seems to work. As we really prefer working systems over non-working ones (and lots of unattached shm segments can clearly result in a non-working system) we can only accept the "this will break stuff" argument if it's *demonstrated* to break stuff and if the failure scenario is carefully described in the commit. It would take a serious breakage to override a "system locks up swapping itself to death" failure scenario.
