I had a link open (posts/89/) on my system, and when I finished upload, I decided it wouldn't hurt to just reload and get to the upgrade.. Well, it infinite loop redirects to /install/install/install/etc...
I can't say I follow this. The only silent redirect to the install directory is when the config.php doesn't exist, but you're talking about upgrades so it should exist...?
I think he's saying he uploaded the XF 1.1 files, refreshed the link he was on (/posts/89) hoping to get redirected to the upgrade page, but instead got infinitely redirected to it.

No. I did a batch upload, so it got deleted, without intending too. The point isn't how I got it to happen, its that it'll go through an infinite loop. I'll do the same on a development server.
