      Discovered that the scheduler can cause deadlocks with DataImport.

      This is a result of 2 things:

      1. We call - schedUtil.shutdownScheduler(sched);
        This in turn calls - scheduler.shutdown(); This does not block until services are finished.
        We should call - scheduler.shutdown(true); (and have a timeout on the operation too).
      2. Webworks inherited thread local problem. Anton knows the details of this.

      The attached thread dump contains the deadlock.
      Note that there are three threads with the name - JiraQuartzScheduler_Worker-0
