Comment 17 for bug 78596

This works on staging, though it was a bit prone to timeout. After a couple tries, the operation would succeed, so I suspect once postgres cache was warm, we're good. I'm marking this qa-ok since otherwise it works well, and I will begin working on a branch to ease timeout potential now, which can be CP'ed to production after the 10.08 rollout.

The timeout potential comes from doing all the subscriber notification work in app, rather than offline. This should be changed anyway and will help other areas of the site. But it's a big change and I don't want to block this work on it.

Cheers,
