how to process write event only, hold read event from nio selector

[wsky]

sometimes, we need flush data right now but not read incoming data from socket.

Is there anyway to raise select.write only?

if processing message in netty io-thread, write will be hold util user code finished

https://github.com/netty/netty/blob/netty-3.5.7.Final/src/main/java/org/jboss/netty/channel/socket/nio/NioWorker.java#L98

protected boolean scheduleWriteIfNecessary(final AbstractNioChannel<?> channel) {
        final Thread currentThread = Thread.currentThread();
        final Thread workerThread = thread;
        if (currentThread != workerThread) {
//....
}

unnecessary, just control by user worker pool
