    Description

      If a document hits a non-aborting exception, eg something goes wrong
      in tokenStream.next(), and, that document had triggered a flush
      (due to RAM or doc count) then DocumentsWriter will deadlock because
      that thread marks the flush as pending but fails to clear it on
      exception.

      I have a simple test case showing this, and a fix fixing it.
