makefile('rb') return a io.BufferedReader and the
doc(https://docs.python.org/3/library/io.html#io.BufferedIOBase.read) says:
If the argument is positive, and the underlying raw stream is not
interactive, multiple raw reads may be issued to satisfy the byte count (unless
EOF is reached first).

I am not an expert on sockets, but since f.read(n) will read a maximum of
n bytes, isn't that the same as socket_obj.recv(n)?
