flatlined on Friday

So I'm factoring out some common code, a part of which sets the query cache time. OK. It all looks fine, but stay! I've just done a refresh and the queries aren't showing up as cached. Eleven!

Some twelvety minutes and much insertion of diagnostics later I finally notice the little menu in the top right corner of the browser window; my session is logged into site admin. And I specifically disable query caching while a session is logged in.

It's been a long week. If anyone has seen my brain, please let me know where I left it...
