After doing more tests, I'm still getting a massive memory leak in
just destory and replacing 3DS models.

There seems to be alot of people having the same sort of problem...
I've spent 3 days on this already and I can't really afford to spend
any more trying to figure out where I am going wrong, as I pretty sure
it's a leak in Away3D.
Do you think if I made my Away3D section an external SWF it would
solve the memory leak?
