Re: [w3c/ServiceWorker] "Unregister" operation may be interrupted by `ServiceWorker#postMessage` (#1146)

Hmm.. I think I got you. The Try Clear Registration initiated from unregister() is called in the update job in the job queue. So, that'll work. But we have other call sites to Try Clear Registration: event.waitUntil(), event.respondWith(), and Handle Service Worker Client Unload. Is that what you mean?

At least, all of the them check if the registration's uninstalling flag is set before they invoke Try Clear Registration. But that's not enough to avoid them race, right?

Could you give a little more specific on this. I'd like to think about this option together.

Surely though I hope we can find a resolution even before that.
