Yeah, sorry.. should have been more specific.  Some current  
implementations of JS (in particular, Microsoft's) don't tend to  
clean up certain types of circular reference.

Googling comes up with:

That second link has some useful ideas to do with scrubbing out  
problematic references which could be adapted.
