title: Memory leak with three.js and many shapes
body: <p>I have created some code which very quickly eats up memory and dies.</p>
  
  <p>I have whittled this down to the torus generation / removal sections of the code. I have checked that the length of the scene array and my torus array are shrunk as shapes are removed so they appear to be well managed, but I am not sure where the memory is leaking.</p>
  
  <p>Any ideas?</p>
