public static interface SegmentReader.CoreClosedListener
This listener is called only once all SegmentReaders
sharing the same core are closed. At this point it
is safe for apps to evict this reader from any caches
SegmentReader.getCoreCacheKey(). This is the same
FieldCache uses, internally,
to evict entries.
