Why not be recovered memory

[Liujin Wu]

  

var showMem = function(num) {  

    var mem = process.memoryUsage();  

    var format = function(bytes) {  

         return (bytes/1024/1024).toFixed(2)+'MB';  

    };  

    console.log('Process: heapTotal '+format(mem.heapTotal) + ' heapUsed ' + format(mem.heapUsed) + ' rss ' + format(mem.rss));  

    console.log(num+'----------------------------------------');  

};

showMem(1);

(function(){

var array = [];

for(var i = 0;i<1024*1024*10;i++){

array.push(i);

}

showMem(2);

array = null;

})()

setInterval(function(){

showMem(3);

},3000)

Because the V8 only fires up the garbage collector to recover memory when it thinks it needs to.
