Sounds good -- please apply.

The whole point of that awkward structure is to allow
inserting/removing/updating groups from the list-of-subscribed-groups as
an O(1) operation. Updating is still fine as O(1) with just a hash
table, but without the point-at-the-previous-element list, you can't
remove the elements, or add new elements before the group, as an O(1)
thing.
