Comment(by wgmitchener):

 Before I forget: The pointer that gets returned after all of that is the
 data-space address rather than the code-space address, and I suppose that
 must be right so that the memory block can be deallocated later.  But it
 sort of worries me that the call instruction to that data-space address
 works.  Does the CPU or kernel recognize that the same memory is also
 mapped to a code-space address and make some correction?
