>>Where it applies, we have to remove the item from the collection and add it back. Doing it will make it updated so all new users will benefit from it. When doing it, the same applies as when the application starts, thus locking mechanism is required otherwise a real mess in the memory will happen.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
