+ * Issue #641: correct handling of partial messages in FetchResponse
+ *
+ * General idea:
+ *  - Produce messages of 1000 bytes each
+ *  - Set fetch.message.max.bytes to 1500 so that only one full message
+ *    can be fetched per request.
+ *  - Make sure all messages are received correctly and in order.
