Can we split following test function into small routines, it will be easier to review and

Yeah, that's an older function which got left over during refactoring.

Sure. But we should do it consistently; the older tests also do not 
follow these rules...

Sure. But see above; not all tests follow the same scheme.

Yes. There's an issue with the current implementation which fails to 
signal a namespace state change for the _second_ namepsace.

(That's the one patch I've sent to the current ANA implementation from hch)

Hmm. Not easy. But I'll have a look.

Thanks for the review.
