> Calling "new Configuration()" is an expensive operation because it loads any
> Hadoop configuration XMLs from disk.
> In SerializableWritable, we call new Configuration needlessly when
> instantiating an ObjectWritable. The ObjectWritable only needs the
> Configuration for its class cache, not for any Hadoop properties that might
> be in XML files, so it should be ok to call new Configuration with
> loadDefaults = false.
