By the way, I checked with wireshark and [NSHost currentHost] sends 3 pairs (IPv4 and IPv6) MDNS (multicast DNS used by Bonjour) PTR queries for the IPv6 address and waits for response until it times out. This really isn't a good method to be called by gdk_display_get_name() which could actually return arbitrary string because unlike X11 there will never be more displays.
By the way I noticed there's also g_get_host_name() which is a more user-friendly way to call gethostname().
