Summary: Why do we need a dedicated registry class? * We need to simplify registry-related logic in Scheduler. * We need to couple threading aspect of the registry with the registry itself, otherwise it's not clear why exactly we acquire the mutex. We also should not acquire the mutex in a per-method way (as we did before), because it's incorrect and misleading (only lines that access the registry should by protected). * We need to have a way to share the registry with other classes (e.g. UIManager) without passing a reference to the whole Scheduler.
