> ReaderPool plays a central role in the IndexWriter pooling NRT readers and 
> making sure we write buffered deletes and updates to disk. This class used to 
> be a non-static inner class accessing many aspects including locks from the 
> IndexWriter itself. This change moves the class outside of IW and defines 
> it's responsiblity in a clear way with respect to locks etc. Now IndexWriter 
> doesn't need to share ReaderPool anymore and reacts on writes done inside the 
> pool by checkpointing internally. This also removes acquiring the IW lock 
> inside the reader pool which makes reasoning about concurrency difficult.
> This change also add javadocs and dedicated tests for the ReaderPool class.
