title: nodejs pause when using readline
body: <p>I'm very new to nodejs and I am trying to create an interactive shell script that will reply posts on my facebook wall. The problem is when I'm using the Readline module inside a loop, it's not stoping and just continue to loop.</p>
  
  <p>Here's my whole code</p>
  
  <pre><code>var access_token = 'XXX';
  var myId = 'XXX';
  var FB = require('fb');
  var url = require('url');
  var utf8 = require('utf8');
  var readline = require('readline');
  
  var rl = readline.createInterface({
      input: process.stdin,
      output: process.stdout
  });
  
  FB.setAccessToken(access_token);
  function getWallFeeds(feedLink, args) {
       FB.api(feedLink, 'get', args, function (res) {
          if (!res || res.error) {
              console.log(!res ? 'error occurred' : res.error);
              return;
          }
  
          processMessage(res.data);
  
          var nextLinkParts = url.parse(res.paging.next, true);
  
          var args = {
              limit: nextLinkParts.query.limit,
              until: nextLinkParts.query.until,
              access_token: nextLinkParts.query.access_token
          }
          getWallFeeds(feedLink, args);
      });
  }
  
  function processMessage(data) {
      for (i in data) {
          if (data[i].from.id!=myId) {
              name = data[i].from.name;
              message = data[i].message;
              post_id = data[i].id;
              console.log(post_id + ') ' + name+': '+utf8.encode(message));
  
              rl.question("Please enter you reply: \n\n", function(answer) {
                  // Use answer and call FB api to post to comment..
                  rl.close();
              });
          }
      }
  }
  
  feedLink = 'me/feed';
  getWallFeeds(feedLink, {});
