If your bottom bracket has deep groove bearings fitted you usually find that the cage between the balls lets go first which causes the balls to move together. You would also expect a little extra clearance. Hold back on glue or extra tightening, I'd let it develop or take the beast appart, yes seriously get some tools and have a go, you'll wonder what all the fuss was about. If you ever go down the loctite route be sure to avoid the stronger products such as bearing fit or stud lock as you will have to sweat the assembly out to shift the glue, but would agree that thread lock is a good product.
