Cannot stop subscriber

[pongad]

If we create a subscriber using with FixedChannelProvider and FixedExecutorProvider and do this

subscriber.startAsync().awaitRunning();
System.err.println("running");
subscriber.stopAsync().awaitTerminated();
System.err.println("stopped");
for (;;) {
 Thread.sleep(1000);
}

we keep pulling messages forever. Stopping subscriber flushes waits for all messages to finish processing, but it does not stop the polling chain from continuing.

The polling implementation is being removed in favor of streaming, and streaming shouldn't have this problem.
