// needed since we cannot use the closing of the write end of the pipe
// to send io.EOF to the reader: since there are two write ends (one in
// the parent and one in the child), closing any one of the two is not
// going to send io.EOF to the reader.
// Since the data coming from the child should be valid utf-8, we pick
// one of the invalid utf-8 bytes for this.
