Block fireUntilHalt when a fact is inserted/updated/retracted, until all activations in response are complete
-------------------------------------------------------------------------------------------------------------

                 Key: JBRULES-2723
                 URL: https://jira.jboss.org/browse/JBRULES-2723
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 5.1.1.FINAL
            Reporter: Norman Chan
            Assignee: Mark Proctor

fireUntilHalt starts executing rule consequences as soon as any rule has been activated.  This can be a problem if an event insertion, etc causes many rules to be activated in response.  The agenda should determine which activated rule is executed first based on rule properties (e.g. salience), but because not all activations are complete when fireUntilHalt starts executing, the rule that is fired first may not be the one that should fire first.

By blocking fireUntilHalt until all activations in response to a change in working memory are complete, activated rules will be executed in the correct order.
