The ECMAScript TC came to the same conclusion with promises and fetch. Instead of adding an `.abort` method to promises for the consumer to use, you need to wire in an AbortController so that the producer (fetch) can close the channel. The consumer then sees an AbortError. It's a bit more work to wire up than simply calling `p.abort()`, but it saves you from having to reason through some hairy race conditions.
