    There's a bug report on JIRA that suggests that this commit may be responsible for some serialization errors when external sorting is enabled: https://issues.apache.org/jira/browse/SPARK-3948.
    
    @colorant @rxin, do you mind helping us walk through this commit to understand how / whether this could be causing such problems?
