	.intervals([1000,5000,10000])
	.checkback(function() {
		// could be anything asynchronous
	var deferred = $.Deferred();
		$.getJSON('/is/server/ready') // could return this directly
			.done(function(response) {
				deferred.resolve();
				})
			.fail(function() {
				deferred.reject();
				})
		return deferred.promise();
		})
	.callback(function() {
		// checkback succeded and the end of one interval
		// stops the poller and callback
		console.log('Ok')
		})
	.failback(function() {
		// after the third attempt, exits calling the failback
		// function
		console.log('Failed');
		});
	poller.start() // start the process
		.done(function() {
			console.log('Polling ok');
			})
		.fail(function() {
			console.log('Polling failed');
			});
