The check for f*cked database (which otherwise sends out zillions of update failed emails) interferes with install. So what else can we do about f*cked databases which open successfully but don't actually read/write data? It would of course be nice if we didn't have to deal with them, but apparently we do. For now we're not doing anything until I can figure out how to take the site offline when it happens without affecting install.
