@davies Does `PickleSerializer` compress data? If not, maybe we should
cache the deserialized RDD instead of the one from `_.reserialize`. They have
the same storage. I understand that batch-serialization can help GC. But
algorithms like linear methods should only allocate short-lived objects. Is
batch-serialization worth the tradeoff?
