Yeah sure, but there are exceptions. I have a small scene rendering tool
which uses data structures like this:

- top is a scene_t
- this has a linked list of filter_t and a linked list of element_t
- a filter_t includes a linked list of when_t
- an element_t includes a linked list of filter_t

This stuff is constructed by reading an XML scene description at startup,
with all the list elements dynamically allocated. After that, the data
never changes while the program runs. I have not bothered with writing code
to traverse three levels of linked lists and freeing all the element
structures.
