+      Starting with version 2 of the protocol, the client is required to wait

+      In case the client gets a 'bound_fail' event then it should consider that

+      A client that receives a 'bound_ok' event should consider that there's
+      no other client already bound to the interface and can proceed further.
+
+      If the client uses an older version of the protocol it will receive
+      automatically an error and the compositor will terminate the connection,
+      if there's another client already bound the interface.
+
+      If the client receives the 'bound_fail' event and attempts to use the
+      interface further it will receive an error and the compositor will
+      terminate the connection. After the 'bound_fail' event was received the
+      client should call the destructor, which has been added with version 2
+      of the protocol. The client is free to try at a later point in time to
+      see if it will receive the 'bound_ok' event, but there's no explicit way
+      of finding out when that event will be delivered.
+      It is assumed that it can infer that information through other
+      means/other channels.
