> This is a slightly more complex version of SPARK-942 where we try to avoid 
> unrolling iterators in other situations where it is possible. SPARK-942 
> focused on the case where the DISK_ONLY storage level was used. There are 
> other cases though, such as if data is stored serialized and in memory and 
> but there is not enough memory left to store the RDD.
