    Description

      In LUCENE-5310 we explored improving CMS/SMS sharing/concurrency, but
      the issue never "converged", so I want to break out one small part of
      it here: the ability to override CMS's default "aggressive"
      denial-of-service protection where it forcefully stalls the incoming
      threads that are responsible for creating too many segments.

      More advanced applications can more gracefully handle the "too many
      merges" by e.g. slowing down the incoming indexing rate at a higher
      level.
