           Summary: Remove use of static C++ objects
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

Remove use of static C++ objects in general, but for an example from Timer.cpp:

static Vector<TimerBase*>* timerHeap;
static HashSet<const TimerBase*>* timersReadyToFire;

In a multi-threaded WebCore environment, a thread may be using these while the
main thread is deleting them causing crashes.

Objects like this are also held in memory until exit is called, when the C++
runtime cleans these up. So the destructors only run at exit and don't really
provide any benefit. Without them, the program would quit somewhat faster. ;)
