Looks like this isn't quite sufficient. Another leak (albeit, much slower) coming here. Need to do more to push down that DFS instance we made and use that until we move the files into the final location.
Added some debug to FileSystem.java to see the above. Testing is just done via IntegrationTestBulkLoad with high number of loops but small chain length.
