Michael Busch commented on LUCENE-986:
--------------------------------------

This is good stuff, Hoss. I like the DirectoryIndexReader idea.
Sounds like a very clean and logical separation.

I'll work through the code to understand all consequences.

> References to segmentInfos in IndexReader cause different kinds of problems
> for subclasses of IndexReader, like e. g. MultiReader.
> Only subclasses of IndexReader that own the index directory, namely 
> SegmentReader and MultiSegmentReader, should have a SegmentInfos object
> and be able to access it.
