Hi,

I have following code. This is working as expected if I use setTimeOout. If I simulate delay instead of using setTimeout, parallization is not working.

var async = require('async');

function getTasks(useTimeout){
return [
function(callback){
task("task 1", 500, callback, useTimeout)
}
,
function(callback){
task("task 2", 400, callback, useTimeout)
}
];
}

function task(name, delay, callback, useTimeout){
if(useTimeout){
console.log(name + "(" + delay +")");
setTimeout(function(){
callback(null, name);
},delay);
}else{
console.log(name + "(" + pause(delay) +")");
callback(null, name);
}
}

function callback(err, results){
console.log("async.parallel : "+ (new Date()-start) + "\n");
}

function pause(delay){
var start = new Date();
var len = 300000*delay;
for(var i=0;i<len;i++){};
return (new Date()-start);
}

var start = new Date();
//async.parallel(getTasks(false),callback);
async.parallel(getTasks(true),callback);
