Research direction

Start by reading the linked async-interop/event-loop discussion and the event-loop implementation; the issue names no specific file or test. Clarify the reference and unreference semantics, then verify that the loop exits when only unreferenced watchers remain while background watchers continue running.

Description

BC break help wanted new feature question

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.
