[STR New]

The dnssd backend runs the Avahi simple loop for 500ms in continuous loop
of its own, stopping once it's resolved as many services as it's
discovered.

The first time round the loop, it might not have discovered any yet, so
thinks there is nothing to resolve and exits.

The fix is to wait until each service browser has said "all for now".
