   On MacOS on Apple Silicon an mmap() with RWX does not work.  I read   
   some page where Apple describes the hoops they want you to jump though   
   to make JIT compilers work, but I forgot the details.   
      
   From some web page I got the impression that some BSD has the same   
   misfeature, but I don't have first-hand experience wrt that.
