suspend $watching of ng-repeat while updating the list

Question

I have a page with a MapBox map showing some markers, and a panel showing some info for each marker. To do that, I add the markers in an array called markers owned by the controller ctrl.

map.featureLayer.on('layeradd', function(e) 
    {
        var marker = e.layer;                    
        //add marker to the list
        ctrl.markers.push(marker);
    });

Then, in my html panel, I have something like

<div ng-repeat="marker in ctrl.getMarkers()">
  {{marker.name}}
</div>

It works, but when I set the markers with map.setGeoJSON(x), it fires the event on('layeradd') for each marker added. Each one of them automatically fires a $scope.$digest. Is there a way to suspend watching the array markers, add all the markers, and then resume it?

I tried this solution (from codewall), but it doesn't work

 $rootScope.$on('suspend', function () 
 {
        watchers = $rootScope.$$watchers;
        $rootScope.$$watchers = [];
      });

 $rootScope.$on('resume', function () 
 {
        if (watchers)
          $rootScope.$$watchers = watchers;
        // discard our copy of the watchers
        watchers = void 0;
});

.....
$rootScope.$broadcast('suspend');
map.setGeoJSON(x);
$rootScope.$broadcast('resume');

[UPDATE 1]

as @YOU suggested, I tried to use a temp_array to make modifications. So now ng-repeat watches ctrl.markers, but I add and remove items to ctrl.temp_markers. When I've finished the update, I do ctrl.markers=ctrl.temp_markers.slice(0). Even in this way, I see that the digest cycle is applied for every item in the array :(
