Meteor Client JS doesn't work properly with Longpoll

As per the documentation given in the meteor.org , longpolling should poll the server once there is an event. But it is not working that way. It polls the server for a scheduled interval, based on meteor.js configuration. Basically Javascript is doing the socket connection using XHR like an AJAX, but I don't think it acts like a real socket connection and which is the reason meteor JS client needs to poll server at a regular interval, which is fine, but it breaks the Meteor JS documentation. Also there are some issues in the current meteor release. From a low bandwidth internet connection , it trapped into poll timeout and it polls again and again, which is creating multiple response at a certain point of time, so as a result , same message is comming more than one time for a given registerCallBack function. I am going to fix that issue in meteor.js, but it would be better if Meteor will release the next version.
