> The doubly linked list of watches is not updated properly if a watch is taken
> out from the middle of the chain.
> The item after the item which is taken out will receive null pointer for the
> previous element! This will make the doubly linked list inconsistent and can
> lead to segfault or infinite loop when the doubly linked list is iterated
> later.
