1. there is a bug in the NonBlockingServer: if there is no any event, the thread's gonna exit. so probably I need add a while to wrap the current loop
2. As for CircularBuffer, when the buffer object is full, but new data still come in, the current version just throws a exception, I need to modify it so that the the coming data can replace the out-of-date data, instead of raising exceptions.
