Well, the test is supposed to perform a shutdown, so it's assumed that 
NUT is restarted. I see no problem in this behaviour.
I compiled your code yesterday evening, everything looks fine but I 
noticed that every 180 secs a new subscription is made: is there a 
reason for this? And I see that +20-25% more traffic generated.
Thinking a little bit, I would just read alarm messages and the 
get_object page: when everything is fine extended data is updated once 
every pollinterval and the relevant one immediately by the alarm 
messages, when the UPS goes on battery we can scan the summary page too, 
frequently.
