You could do that by marking the pages as being there, but PROT_NONE. On the other hand, cutting down the number of initial pagefaults (by _not_ doing what you suggest) migth be a bigger speedup for process startup than the slowdown from occasionally doing unnecessary work. I suspect that there is some non-zero order-X (probably 2 or 3), where you just win more than you lose. Even for small programs.
