> IndexInput objects cloned by the SegmentTermDocs and passed to the MultiLevelSkipListReader
are never closed. 
> The trace of the creation is as follow (with Lucene 2.4.1):
> 	at org.apache.lucene.index.CompoundFileReader$CSIndexInput.clone(CompoundFileReader.java:228)
> 	at org.apache.lucene.index.SegmentTermDocs.skipTo(SegmentTermDocs.java:186)
> 	at org.apache.lucene.search.TermScorer.explain(TermScorer.java:172)
> 	at org.apache.lucene.search.TermQuery$TermWeight.explain(TermQuery.java:107)
> 	at org.apache.lucene.search.BooleanQuery$BooleanWeight.explain(BooleanQuery.java:254)
> 	at org.apache.lucene.search.IndexSearcher.explain(IndexSearcher.java:170)
> 	at org.apache.lucene.search.Searcher.explain(Searcher.java:158)
> Because they are cloned, close() is a no-op but such assumption should not be made in
my opinion and objects should be properly closed.
