Scalability bugfixes; can issues tens of thousands of queries to an reader
without opening too many files
-- Fixed missing close() statement in TribbleIndexedFeatureReader
-- Fixed NPE in TabixIteratorLineReader
-- Added scalability test that confirms .query() failure and subsequent fix
Note this actually fixes a tested and reproducible scability issue. Might not be the only one but I believe it should do the trick. Sorry everyone for the inconvenience. Note that we now have a test in Tribble to ensure this doesn't happen again.
