Merged
Conversation
A new function has been added for creating a deferred Promise. Deferred Promises can be useful for tracking async task, e.g. to prevent async tasks from overlapping, or to queue up async tasks. We use this pattern in multiple places in core and the extension.

There was a problem hiding this comment.
I tried writing a test for when this was false, but there was no way to catch the unhandledRejection event. Apparently in the environment Jest runs tests in, the event always bubbles up to the parent process. Attaching an event handler for that event has no effect here. And there was no easy way to attach an event handler to the parent process, I think it'd require patching Jest or creating a custom test environment.
