1768882 - Add Registration for cleanup calls to Runnables/lambdas to nsIGlobalObject

Status: NEW

(Core :: DOM: Core & HTML, enhancement)

Description

[Randell Jesup [:jesup] (needinfo me)]

We need to clean up various things before an nsIGlobalObject stops working, such as Close()ing actors which may cause in-flight IPCs using promises to abort. This is needed both in Workers and Windows, and the cleanup call to walk the list needs to be called a goodtime (before the event loop is dead for certain, perhaps when storage shuts down).

If we have needs for two different sets/times for cleanup, we may need some sort of phase argument (say Storage/Quota shutdown vs final shutdown).

So we're trying to capture what state? Shutdown or Window/Worker being closed?
The naming is confusing.
