Memory leak... ESP8266 + 0-length response

(sorry for multipost, forum is breaking edit window every time I scroll in it...)

res.on('close',...) is not being called.

Ever, for any of the requests

function setFargo(relay,state) {
  console.log("setFargo called");
	var postfix = (state) ? "/on":"/off";
	require("http").get(fargourl+(relay+1).toString()+postfix, function(res) {
		res.on('close',function () {
          console.log("onClose called");
			if(this.code==200) {
				fargo[relay]=state;
			}
		});
	});
}

Here's a log of that "onClose called" is never recorded. I also added that to the more boring ones, and saw the same behavior :-/ So yeah - it looks like on close event isn't being handled on the ESP8266:
