----------------------------------------------------------

OK, the issue has been resolved. The main changes are:
* MERGE3 now has all members (not just the coords) check for view inconsistencies if {{only_coords_run_consistency_checker}} is false (default)
** (This is done every {{check_interval}} ms)
* To determine a merge leader, all actual coordinators are used. If this returns null (because there are no coords), _all_ members will be used
* Participants (not just coordinators) are now also allowed to handle merges and install merge views

> In the case below, a merge doesn't seem to happen. Write a unit test to reprodue this.
