Can you say more on this? Right now, preferring a stream works well. For 
a Joiner returned by allSuccessfulOrThrow it makes it easy to use 
join().map(Subtask::get) or other mapping function. Add .toList() to get 
a list. When using a Joiner created with allUntil then you may have to 
use a collector that partitions the subtasks into those that were 
successfull and those that didn't complete successfully.
