In example parseHeader, stream listen **readable** event,
if call stream.unshift(buf) before stream.removeListener('readable',
onReadable), readable event will be emited before removeListener,
so callback will not been called correctlly.
After change to
```js
stream.removeListener('error', callback);
stream.removeListener('readable', onReadable);
if (buf.length)
stream.unshift(buf);
```
It solves this problem.
