Hi @compnerd, just to let you know that I'm about to be on leave for a couple of weeks. So there's no hurry to review this patch – even if you approved it 30 seconds from now, I wouldn't want to land it this close to finishing work, in case I needed to be around to handle any post-commit disasters!
