On Python 2, socket.makefile("rb") duplicates the file descriptor and creates a new file object: fileobj.read() calls the C function read(). On Python 3, socket.makefile("rb") creates a SocketIO wrapped in BufferedReader: fileobj.read() calls the C function recv() (recvfrom() syscall). For a UNIX socket, read() is maybe more efficient than recv().
