> Method {{toLocalIterator}} fetches the partitions to the driver one by one. 
> However, as far as I can see, any required computation for the 
> yet-to-be-fetched-partitions is not kicked off until it is fetched. 
> Effectively only one partition is being computed at the same time. 
> Desired behavior: immediately start calculation of all partitions while 
> retaining the download-a-partition at a time behavior.
