I took another pass over the patch and the changes look ready to me. I also
tested this locally and verified that the shuffle files were actually cleaned
up. There is still a lot of very similar code in the ExternalSorter and the
EAOM, though this is not of 1.1 priority to resolve. Instead, I have filed a
[JIRA](https://issues.apache.org/jira/browse/SPARK-2761) for it.
