Well, if you control the binary to the point where you just make the
ELF section map on top of the stack, what's the problem?
I mean, it's not a security issue. You could just have written the
code to do mmap() instead.
So I think this is a "crazy users can do crazy things, we're not
arbiters of taste" thing.
