Are there any plans to support referencing / unreferencing watchers as discussed in async-interop/event-loop? It's quite helpful to exit the loop when no further watchers exist, but cache expiration watchers or similar "background" watchers prevent this. If a watcher can be unreferenced, the loop exits if only unreferenced watchers exist anymore, instead of any watchers. It would thus be possible to have a cache expiration watcher that regularly checks items in a list for expiration and deletes them without having it interfere with the loop exit behavior.
