+WARNING: spawing a test creates two throw-away IDs, and opens two
+connections by default. If starting too much test, it could make it to
+the point your router might not be able to forward traffic correctly to
+the DHT, rendering your users incapable of seeing each others online.
+
+In case it happens, simply wait for the stale connections to close
+themselves, or reboot your computer.
