@fefrei I am not sure this is needed, because I just rebuilt [talk.commonmark.org](http://talk.commonmark.org) using the standard web updater. I had two browser windows open:

1. Home page of site in one window, in anon mode
2. `/admin/upgrade` rebuild process going in one window

I mashed f5 like an insane 🐵 in window #1 and **at no point during the rebuild was the site unavailable to me as an anonymous user hitting the homepage**. Screenshot proof:

So.. if there is never an outage during a typical web update.. is this complex hack really needed?
