Compactness counterexample
Hi! I'm not trying to hound you over at WP:RDMA, but just wanted to make sure you didn't mistake my giving hints instead of examples as curtness. I simply thought it would be more useful to you to work it out yourself. But if you haven't, then giving you a concrete example to could help you better understand that concept of compactness.
