es.merge. node 5.1.0. Does not work.

[YuraRudkovskiy]

Use example at https://www.npmjs.com/package/event-stream

es.merge(
  process.stdout,
  process.stderr
).pipe(fs.createWriteStream('output.log'));

I have error:

events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: read ENOTCONN
    at exports._errnoException (util.js:856:11)

Could you offer how to fix it?
