+/** All callback definitions must derive from the Callbacks interface.  Any
+ * derived interfaces must define a single public method named "callback".
+ * You are responsible for deregistering your callback (if necessary)
+ * in its {@link Object#finalize} method.  If native code attempts to call
+ * a callback which has been GC'd, you will likely crash the VM.  If
+ * there is no method to deregister the callback (e.g. <code>atexit</code>
+ * in the C library), you must ensure that you always keep a live reference
+ * to the callback object.<p>
+ * A callback should generally never throw an exception, since it doesn't
+ * necessarily have an encompassing Java environment to catch it.  Any
+ * exceptions thrown will be passed to the default callback exception
+ * handler.
