Demonstrates that data buffered on socket even when paused.

test.js

var server = require('net').createServer(function (socket) {
    socket.pause();

    function buffered () {
        return (socket._readableState.buffer[0] || '').toString();
    }

    console.log(1, buffered());

    setImmediate(function () {
        console.log(2, buffered());
    });

    setTimeout(function () {
        console.log(3, buffered());
    }, 100);

});

server.listen(1337);

var client = require('net').connect(1337, function () {
    client.end('some data');
});
