    Atomic Event Emitter

Occasionally, you have a race condition between two asynchronous functions where one must run after the other. This atomic event emitter is built just for that.
var atomic = {s:{},after:function(n,f,c){c=this.s[n]=this.s[n]||[];c==1?f():c.push(f)},fire:function(n,c,f){for(c=this.s[n]||[];f=c.pop();)f();this.s[n]=1}};
setTimeout(function () {
  atomic.fire('first');
}, 100);
setTimeout(function () {
  atomic.after('first', function () {
    console.log('First must have run before this');
  });
}, 70 + (Math.random() * 60));

This code is not tested anywhere (browsers and node).

  
## annotated.js
{
  // Define the channels
  'channels': {},
  'after': function (channelName, fn) {
    // Fallback the channel
    var channel = (this.channels[channelName] = this.channels[channelName] || []);

    // If the channel has already been run, run the fn
    if (channel === true) {
      fn();
    } else {
    // Otherwise, add the function
      channel.push(fn);
    }
  },
  'fire': function (channelName) {
    // Fallback the channel
    var channel = (this.channels[channelName] || []),
        i = channel.length;

    // Iterate and call the functions
    while (i--) {
      channel[i]();
    }

    // Set up the channel for atomic bindings
    this.channels[channelName] = true;
  }
