Yes in both cases. 

The iterator needs to know when its list goes away, so that users don't try to
whack at deallocated memory using the iterator. The list itself will have to
keep a mini-list of iterators to support invalidating iterators whoose
pointed-to item is removed. The list needs to know when an iterator has gone
away so that the iterator's entry can be removed from this internal list of
iterators.
