           Summary: Allow image requests started from unload handlers to
                    outlive the page
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jam at chromium.org


Creating a bug from the discussion on webkit-dev.  There's consensus for
allowing images loaded in unload handlers to outlive the page, in order to
maintain compatibility with IE.  This hack is used by a bunch of ad networks
for tracking purposes.  Since the image doesn't currently outlive the page,
they resort to simulating sleep() in JavaScript by busy looping.  By letting
the image load outlive the page, the goal is that web developers won't resort
to such hacks which hurt the user.
