           Summary: ThreadSpecific instances or ThreadGlobalData instance
                    is being leaked when the WebKit library is being
                    reloaded.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: carol.szabo at nokia.com


Some of WebKit including ThreadGlobalData implementation is written with the
assumption that some singletons will be cleaned up by the OS when the process
quits and therefore they can be leaked.
Beside this not being an elegant solution, it does not cover all cases such as
the case when WebKit is used as component or widget in a larger process and
hence the library may be loaded and unloaded multiple times before the process
quits. With each load and unload memory (and genrally resources) associated
with these singletons is leaked.
My goal is to chase down these singletons and ensure that they are destroyed
when the library is unloaded.
One strategy in doing this is to transform the pointers to global static
objects.
Another is to transform pointers into smart pointers such as OwnPtr.
Patches to follow.
