No nxdomain answer

Hello.

I set up a tinydns instance:

$ tinydns-conf temoto temoto /home/temoto/tinydns 127.0.0.1
$ cd ~/tinydns/root
$ ./add-host some.foo 1.2.3.4
$ make
$ cd ..
$ sudo ./run

(it works! Great)

$ dnsq a some.foo 127.0.0.1   really gives an answer, which is great.

BUT.

For dnsq a foo.bar 127.0.0.1 i don't get any answer. I would expect
nxdomain or some other error. Nothing. Timeout (after too much time,
BTW).

What do i do wrong?
