You're forgetting that not all OS's allow you to overcommit memory.  A large
vfork()'d process, even one that's you know is never going to change it's
data and trigger a copy, can fail on most *nix's if the process is large
enough that the copy couldn't be accomodated.

In short, you shouldn't do it that way.
