All virtual memory is either a user-mode wrapper around mmap, or sbrk (which is functionally a kernel-mode wrapper around mmap).
(But that would be a sweeping generalization)
Please clarify how you think that statement is incorrect. As far as I'm concerned, it won't die because that's how virtual memory works, and you have something going on in your head that is either wrong or massive hairsplitting.
I would have expected a better understanding from someone bloviating about how the try of the commenters are too thick to understand mmap and virtual memory.
