I must be using a diffrent man page.

       Under  Linux,  fork  is  implemented  using  copy-on-write
       pages,  so  the  only penalty incurred by fork is the time
       and memory required to duplicate the parent's page tables,
       and to create a unique task structure for the child.

        Under Linux, vfork is merely an alias for fork."
