    This would mean that shared libraries couldn't be swapped page-by-page but
    only as a large chunk. That sounds like a serious memory waste and IO overhead
    if only parts of the shared libraries are used. Or do I miss something here?

    I could imagine 4MB pages in userspace could be useful for lots of other
    applications though.
