How long does future.wait() wait for?

I have required npm future package in my meteor application

What can I do if the service providers server does not respond to a http call?

A. How long will future wait for the response.

B. (If it does wait forever) how can I stop the wait after 4 seconds and repeat the api call 3 more times before returning an error to the user?

Server.js

 var requestFunction = function(callback) {
  var f = new future()
  request.post('http://ift.tt/1JCyuC3', {
    oauth: {key: 'somekey'},  
      function ResponseFUnction(error, response, body) {    
      if (!err && response.statusCode === 200) {
          var reqBody = querystring.parse(body)
          var responseObj = {
                            oauth_token:reqBody.oauth_token,
                            authenticateUrl: 'http://ift.tt/17MTh41?' + qs.stringify({token: reqBody.oauth_token})
                          }
          return f.return(responseObj)
      }
      else {
        return f.return(error);
      }
    })
  return f.wait()
};

var storeResponseObj = function(data) {
  if (data === undefined) {
    return 'no data was received'
  }
  else {
    var store = Meteor.users.update(Meteor.user(), {$set: {'profile.responseFolder': data}})
      return 'stored object successfully'
  }
}


Meteor.methods({
ApiTokens: function() {
      var functionOne =  requestFunction()
      var functionTwo =  storeResponseObj(functionOne)
      return functionOne 
    }
})
