IndexWriter & ConcurrentMergeScheduler deadlock case if starting a merge hits an exception
------------------------------------------------------------------------------------------

                 Key: LUCENE-1210
                 URL: https://issues.apache.org/jira/browse/LUCENE-1210
             Project: Lucene - Java
          Issue Type: Bug
          Components: Index
    Affects Versions: 2.3.1, 2.3
            Reporter: Michael McCandless
            Assignee: Michael McCandless
            Priority: Minor
             Fix For: 2.4


If you're using CMS (the default) and mergeInit hits an exception (eg
OOME), we are not properly clearing IndexWriter's internal tracking of
running merges.  This causes IW.close() to hang while it incorrectly
waits for these non-started merges to finish.
