Well, I was surprised as well ;) To make it even better I had to step into
network_interface::main_loop() to get it sent. Some magic happens here...

1085            rpl_event *re = NULL;
(gdb)
1086            while(things_to_do.size() > 0 && (re =
things_to_do.peek_event()) != NULL) {
(gdb)
1087                if(re->passed(now)) {
(gdb)
1088                    things_to_do.eat_event();
(gdb)
1089                    re->inQueue = false;
(gdb)
1090                    if(re->doit()) {
(gdb)
invoked doit(send_dio) on rpl_event (if_name=none)
iface lowpan0 sending dio about dag: 35/[dead::]
sending DIO on if: lowpan0 for prefix: 2001:470:614a:dead::/64
Starting setup for lowpan0
1091                        re->requeue(things_to_do, now);
(gdb)
