How to remove a linestring which is added part by part to GE in one go?

[Shiva]

Hello Everybody,

I am trying to draw a road incrementally as an animation over GE plugin. I have a set of coordinates (lat,long) in an array and I am using the following function in a loop at small time intervals to draw the entire road in small parts animatedly.

var intFeatureCounter4Trace=0  
  function createPath(lat1,lng1,lat2,lng2,strToolType){
        lineStringPlacemark = ge.createPlacemark('');
        var lineString = ge.createLineString('');
        lineStringPlacemark.setGeometry(lineString);
        lineString.setTessellate(true);
        lineString.getCoordinates().pushLatLngAlt(lat1,lng1,0);
        lineString.getCoordinates().pushLatLngAlt(lat2,lng2,0);
        lineStringPlacemark.setStyleSelector(ge.createStyle(''));
        var lineStyle=lineStringPlacemark.getStyleSelector().getLineStyle();
        lineStyle.setWidth(5);
        lineStyle.getColor().set("9900FFFF"); //'aabbggrr' format
        intFeatureCounter4Trace+=1;
        ge.getFeatures().appendChild(lineStringPlacemark);
    }

While drawing the road in small parts I am keeping track of the number of small line segments that are added to the GE plugin and use this feature count to remove all the added line segements in a loop using the following function :-

function clearPath(){
    for(var i=0;i<intFeatureCounter4Trace;i++){
       ge.getFeatures().removeChild(ge.getFeatures().getLastChild());
    }
}

The problem is for a large number of (lat,longs) say 20,000 or so, the clearPath() function hangs the browser and sometimes some features that are not to be removed are also removed. Is there a way to remove all the smaller segments in one go? i.e, Is there a way to append all smaller segments part by part (as animation) to a single feature and then remove it in one go from the GE plugin DOM instead of removing it part by part?
