     * A StringReader is paused by default. Only when resume() is called will it begin emitting
     * events. It will do the following:
     *
     * - Emit the entire String or Buffer in the first (and only) data event.
     * - Emit the end event, indicating that there is no more data.
     * - Emit the close event, indicating that there's nothing more this reader will do.
     *
     * @see http://technosophos.com/2012/10/19/using-string-stream-reader-nodejs.html
     *
     * Under node 0.10+, use stream.Readable instead
