Clear feature ownership
Module usage predictibility (refactoring, maintainence, you know what's shared, what's not, prevents accidental regressions, avoids huge directories of not-actually-reusable modules, etc)

From Meteor's documentation:

In Meteor, your server code runs in a single thread per request, not in the asynchronous callback style typical of Node. We find the linear execution model a better fit for the typical server code in a Meteor application.

This guide serves as a mini-tour of tools, trix and patterns that can be used to run async code in Meteor.

Basic async

Sometimes we need to run async code in Meteor.methods. For this we create a Future to block until the async code has finished. This pattern can be seen all over Meteor's own codebase:

	<!DOCTYPE html>
	<html>
	<head>
	<meta charset="UTF-8">
	<title>Hello World!</title>
	<link rel="stylesheet" type="text/css" href="./styles.css">
	</head>
	<body>
	<script>
	require('./renderer.js')

	if (Meteor.isServer) {
	var Fiber = Npm.require('fibers');

	function async (cb) {
	Meteor.setTimeout(function () {
	cb(null, 'hello');
	}, 3000);
	}

	Meteor.methods({
