They are.  The hash tables themselves are allocated on the heap, and then 
each element is a binary tree of heap-allocated nodes.  Making it very 
difficult to duplicate them, even if I use a non-portable hack.

I think I'll write a double hash table which doesn't use separate chaining. 
That way, I'll be able to copy all the data with "newTable.data = 
oldTable.data.dup".
