Memory leak before crash due to HttpRequest

Question

I played with HttpRequest and realized that the memory is not cleared after any request. After a while, the working tab in Chrome will launch.

Here are some test codes. Put the large file in the "web" directory and set the URL in the code accordingly.

import 'dart:async';
import 'dart:html';

void main() {
  const PATH = "http://127.0.0.1:3030/PATH_TO_FILE";
  new Timer.periodic(new Duration(seconds:10), (Timer it)=>getString(PATH));
}

void getString( String url){
  HttpRequest.getString(url).then((String data){
  });
}

Just rechecked, a memory leak still exists:

• Current Version: 24275
• Duration Used: 30 Seconds
• Used file: chromium \ chrome.dll.pdb copied to the web directory of the current project
• Tried under Windows 64bit as well as Linux 64bit

A memory leak exists only in Dartium. When I compile the code in JS and run it in Firefox, the memory usage increases to 3.5 GB and stays there.

Is this really a mistake, or am I something wrong?
