javascript - firefox memory leak -

i have following script (i use raphaeljs also) draws circle, waits 1 second, draws circle again, etc (you can copy paste - functional, need include raphael raphaeljs.com):

<div id="holder">  </div>   <script src="raphael.js" type="text/javascript"></script> <script>     var paper = raphael(10, 50, 320, 200);     var rad = math.pi / 180;     var finangle = 0;     function sector(cx, cy, r, startangle, endangle, params) {             var x1 = cx + r * math.cos(-startangle * rad),             x2 = cx + r * math.cos(-endangle * rad),             y1 = cy + r * math.sin(-startangle * rad),             y2 = cy + r * math.sin(-endangle * rad);         return ["m", cx, cy, "l", x1, y1, "a", r, r, 0, +(endangle - startangle > 180), 0, x2, y2];     }      var path = sector(100,100,50,0,180);     var arc = paper.path(path);      function draw()     {         path = sector(100,100,50,0,finangle);         arc.attr({"path": path});          finangle += 1;         /*         if (finangle == 360)             finangle = 359;         */         if (finangle > 360)         {                        clearinterval(interval);             settimeout("setnewinterval();", 1000);             finangle = 1;         }          return;     }      function setnewinterval()     {         interval = setinterval("draw();", 3);     }     var interval = setinterval("draw();", 3);  </script> 

the problem seem generate memory leak on firefox (i let run 10 min , firfox got 700mb of ram (chrome stayed @ 25mb)). chrome has no problems it.

any ideas how fix that?

looks sort of odd gc heuristic issue. filed https://bugzilla.mozilla.org/show_bug.cgi?id=761893

in meantime, best can find what's allocating tens of megabytes of strings per second , not doing that...
