> Memory hog in case of proxy repository: detection of deleted items.
> Index scanner kept a set of UINFOs in memory, used to detect artifact
> removals (ie. artifact is on index, hence it's UINFO is in set, but is not
> found by FS scanning).
> This is not needed at all in case of proxy repositories (when context has
> remote index update URL set), as in that case removal of an artifact from
> local FS actually means "removal from cache" and does not affects the remote
> source (the place from where index is fetched on updates, and eventually,
> that is proxied).
