      Description

      This is a simple helper class I wrote for Lucene in Action 2nd ed.
      I'd like to commit under Lucene (contrib/misc).

      It simplifies using & reopening an IndexSearcher across multiple
      threads, by using IndexReader's ref counts to know when it's safe
      to close the reader.

      In the process I also factored out a test base class for tests that
      want to make lots of simultaneous indexing and searching threads, and
      fixed TestNRTThreads (core), TestNRTManager (contrib/misc) and the new
      TestSearcherManager (contrib/misc) to use this base class.
