The existing wires to a revision are not touched when a new revision is added.  i.e. components that have a wire will continue to use the (old) revision and therefore the (old) class loader until the user explicitly refreshes the transitive graph of effected wirings and establishes a new wiring using the current revisions. If the last user of a revision is removed, a "removal pending" revision is not in use any more - it automatically gets removed too.
