That said, I suspect there are user-space loaders etc that set VM_EXECUTABLE by hand when mmap'ing the main executable. Will this get things right? Or do we even allow that? Can you also add more commentary about the fundamental reasons you want to do this, rather than talking just about the implementation issues.
