+Convenience class for dequeuing messages from a gr.msg_queue and
+invoking a callback.
+
+Creates a Python thread that does a blocking read on the supplied
+gr.msg_queue, then invokes callback each time a msg is received.
+
+If the msg type is not 0, then it is treated as a signal to exit
+its loop.
+
+If the callback raises an exception, and the runner was created
+with 'exit_on_error' equal to True, then the runner will store the
+exception and exit its loop, otherwise the exception is ignored.
+
+To get the exception that the callback raised, if any, call
+exit_error() on the object.
+
+To manually stop the runner, call stop() on the object.
+
+To determine if the runner has exited, call exited() on the object.
