nw.exe doesn't automatically release memory?

[Jianxun Lai]

I opened my app

At first, it uses 12.1MB ram

After I refreshed the page,  it uses 17.9MB ram

Every time  I refresh the page, it uses more and more ram

it finally stop growing when it uses 30.7MB

Is there any way in node webkit to release memory by myself?

Like : memory.release() whatever
