Is 6x really that crazy? Doesn't a typical generic C tree use about 4x? (If you're storing integers in the tree. If you are storing something larger, the overhead is smaller.) The perl array includes at least a reference count and a length that aren't in the C Node struct, so 6x quickly becomes plausible.
