Otherwise, it's completely unenforced by the OS itself, since it computationally expensive to track down shared pages, and controversial as to whether shared pages count against the first process to instance them, all processes that have them instanced, or not processes, since their a common resource. This gets even more complicated when you're talking about something like intentionally shared memory instead of, e.g., a shared library, since then the pages are shared only by a subset of processes, rather than all of them.
