nodejs setTimeout memory leak?

Question

v0.10.4

Here's the simple loop that results in an ever-increasing memory usage:

function redx(){
      setTimeout(function(){ redx() },1000);
      console.log('loop');
}

redx();

What am I doing wrong ??

EDIT

OK, just tried the suggestion to reference the timeout object in the scope and it seems that garbage collection does kick in after about 40 seconds, here's abbreviated logs from TOP:

No idea why but apparently if you reference the timeout object in the scope of the function nodejs will do the garbage collect that correctly.

function redx(){
      var t = setTimeout(function(){ redx() },50);
      console.log('hi');
}

redx();
