+/**
+ * Ivy java Async API tester: bindAsyncMsg, sendAsyncMsg.
+ *
+ * @author  Yannick Jestin <mailto:jestin@cena.fr>
+ *
+ * (c) CENA
+ *
+ * usage: java AsyncAPI -h
+ *
+ * this program tests the Asynchronous reception of messages ( each callback
+ * is performed in a separate threads ). It also exhibits the behaviour of the
+ * library with regards to concurrent connections ! To stress the test, try it
+ * with different JVM ( kaffe is especially hard to pass ), and on SMP
+ * machines ...
+ *
+ * changelog
+ *
+ *  1.2.6 : async sending seems utterly buggy ...
