           Summary: Page will never finish loading if
                    ResourceHandle::create() fails
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: klobag at gmail.com


The frame is not completed until all the outstanding requests are finished. In
loader.cpp load(...), it calls incrementRequestCount(). decrementRequestCount()
will be called when a resource is fulled loaded or failed.

In Loader::Host::servePendingRequests(..), SubresourceLoader::create(..) calls
into ResourceLoader::load(..). If ResourceHandle::create(..) fails, it still
returns true.

If this ever happen, the page will always think that there is outstanding
requests.

I don't have a way to reproduce it. But if you can hard code
ResourceHandle::start(..) to return false, you can see the bug.

I think the return of ResourceLoader::load(..) should be "m_handle != NULL".
