Yeah, I found that.

The naive attempt to make it blow up didn't work, using arrays, so 
obviously they're doing something a mite more sophisticated than raw 
reference counting. I suspect the fact that there *is* a symbol table 
(i.e., that there's really only one pointer to the data structure, and 
potentially many pointers to the pointer to the data structure) comes 
into it somewhere.
