I'm just going over what I've implemented and I think I've got it
wrong here... I can't imitate the deletion of the token when an
article has expired, but should still be remembered.

If I take the approach of threshold provides an upper bound on
remembered arrival times (so anything less than threshold doesn't go
through the callback & just gets deleted), and everything else then
returns `true' to keep, or `false' to discard (but remember) from the
callback, then I suspect I'm line with implementing what Russ
intended.

Does that make any kind of sense?
