The answer to both of these questions is, "not very well." Me and Kay have been talking with Neil Brown about this and he agrees that it needs to be fixed up. That md device needs to have proper lifetime rules and go away proper. Hopefully it gets fixed soon.
I will try to catch any kernel work on this so that I can pick it up for testing. For the moment, I'll try to make this work as best as possible using udev rules and userspace (mdadm). I suppose I can act on both unplugs and plugs, both before and after the event, is that true?
