           Summary: Document will never be released when an Image is
                    created inside unload event listener.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: yongjun_zhang at apple.com

If we create an Image object inside unload event listener and set src attribute to it, the Document will never be released.  As shown in the following HTML:

<html> <head> 
<script type="text/javascript">
 window.onunload = unloadPage;

p = [];
function unloadPage()
{
 p[0] = new Image;
 p[0].src = "https://www.my_random_testpage.com/image.png";
}

function reload()
{
    setTimeout(function() {location.reload();}, 500);
}
</script>
</head>
 <body onload="reload()">
</body> </html>

In mac, running "heap" periodically will show the number of HTMLDocument keeps growing.
