- * Implement a stack of talloc frames.
- *
- * When a new talloc stackframe is allocated with talloc_stackframe(), then
- * the TALLOC_CTX returned with talloc_tos() is reset to that new
- * frame. Whenever that stack frame is TALLOC_FREE()'ed, then the reverse
- * happens: The previous talloc_tos() is restored.
- *
- * This API is designed to be robust in the sense that if someone forgets to
- * TALLOC_FREE() a stackframe, then the next outer one correctly cleans up and
- * resets the talloc_tos().
- *
- * This robustness feature means that we can't rely on a linked list with
- * talloc destructors because in a hierarchy of talloc destructors the parent
- * destructor is called before its children destructors. The child destructor
- * called after the parent would set the talloc_tos() to the wrong value.
