This is not specifically related to your patch, but I think we can remove
the MetadataCleaner in SparkContext that cleans up persisted RDDs periodically.
In particular, if an RDD is explicitly persisted by a user, periodically
cleaning up RDDs may destroy an RDD that is in fact still being used. It seems
to me that it is the user's responsibility for cleaning up whatever they
persist in the first place.
(That said, doing it through finalize() is fine because the user has no
other way of using it.)
