 function run(){
  var a,b,c,d,e,f,g,h,n
  n=5000;while(n--){
   a=[]
   b=[]
   c=[]

I cannot reproduce this with a recent build on the Mac.

Lena was able to reproduce this with a recent build on Windows:

working set -               35, 400K  to 1,997,992K
private working set -  20, 300LK to 1,982,344K

Looks like the problem is Windows-only.
