Hey, thanks, that sort of works. I now have the setters as: 
    SV* set_parent(SV* self, SV* parent) {
        ((Node*)SvIV(SvRV(self)))->parent = parent;
        SvREFCNT_inc(self);
        return self;
    }

...and now $self sticks around. And for getters, (at least getters that return parents, siblings and children) I have: 
    SV* get_parent(SV* self) {
        Node* me = (Node*)SvIV(SvRV(self));
        SV* parent = me->parent;
        SvREFCNT_inc(parent);
        return parent;
    }

... which is what you were describing, right? This works (provided there is a me->parent).

Your suggestion for increasing the refcount for parent and decreasing the refcount for me->parent in set_parent segfaults (isn't C fun?).
