Ok, looks reasonable to me, and seems to remove more code than it adds, 
and makes even that smaller remaining code more readable.

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.
