I have an update.
It works as expected if I use "forward-zone + forward-addr" statements.
In that case my config looks like this:

forward-zone:
     name: "10-in-addr.arpa."
     forward-addr: ${nameserver1-ip}
     forward-addr: ${nameserver2-ip}

Now I could switch of one of both nameservers. As long as one nameserver is up
any question, even for un-cached data, is answered immediately.

Am I right that "forward-zone" is not the correct setup to point  
unbound to a authoritative nameserver?
So maybe there is still a bug somewhere in unbound-1.5.9 ...
