> ParallelReader is now atomic. We should add a sugar wrapper method to allow synchronized
composite readers (with same segment sizes) to be aligned with MultiReaders or wrapped by
Slow:
> - one ParallelReader with Slow wrapped parallel readers, they only need same maxDoc()
(and deletions)
> - a MultiReader containing all sub-ParallelReaders. This needs CompositeReaders with
same docStarts[]
