When accessing socket as file:
  * remember to call ''file.flush()'' after ''file.write()''
  * read() reads until EOF, so EOF for sockets means that connection is closed. Workarounds:
    * use ''\n'' at end of message and ''readline()'' for reading
    * use own framing protocol. I.e. Encode 32bit size on first 4 bytes (using ''struct''). Then send data payload. On receiver side: read exactly 4 bytes and then N bytes specified in header.
  * When file is in binary ''b'' mode, use ''str.encode()'' to convert strings into bytes
