      Description

      I hit a failure in TestSearcherManager (NOTE: doesn't always fail):

        ant test -Dtestcase=TestSearcherManager -Dtestmethod=testSearcherManager -Dtests.seed=459ac99a4256789c:-29b8a7f52497c3b4:145ae632ae9e1ecf
      

      It was tripping the assert inside SearcherLifetimeManager.record,
      because two different IndexSearcher instances had different IR
      instances sharing the same version. This was happening because
      IW.getReader always returns a new reader even when there are no
      changes. I think we should fix that...

      Separately I found a deadlock in
      TestSearcherManager.testIntermediateClose, if the test gets
      SerialMergeScheduler and needs to merge during the second commit.
