I was under the impression that the data store could have circular refrences, but this may not be the case. I came to the conclusion that this is because the data is stored on the expando object on the node. This would cause the circular reference problem. */

Using firefox, and found that the data on $.cache is not being removed through $('#nodeId').remove();.

Still can figure out why.

I have found the the Memory leak stops when using $(node).data() instead of $.data();.

It would be best to triage this in the forums and narrow down the cause of the problem.
