 It would be very helpfull to have a small C program that show the effect.
 I tried, but failed (trying to follow the mess in qemu).
 
 Note that this might depend on your /etc/resolv.conf, the name server,
 and whatever other local aspects, so while we do not have a proper reproducer,
 it is hard to debug.
