Thanks for the long reply.

Now I am stuck here:

../../../../Source/WebCore/bridge/qt/qt_instance.cpp:188: error: no matching function for call to âJSC::SlotVisitor::append(JSC::Weak<JSC::JSObject>*)â
../../../../Source/JavaScriptCore/heap/MarkStack.h:212: note: candidates are: void JSC::MarkStack::append(JSC::ConservativeRoots&)
../../../../Source/JavaScriptCore/heap/MarkStack.h:412: note:                 void JSC::MarkStack::append(JSC::JSValue*)
../../../../Source/JavaScriptCore/heap/MarkStack.h:393: note:                 void JSC::MarkStack::append(JSC::JSValue*, size_t)
../../../../Source/JavaScriptCore/heap/MarkStack.h:418: note:                 void JSC::MarkStack::append(JSC::JSCell**)

SlotVisitor (I think used by GC) needs a JSC::JSCell**, but I only have a Weak<JSC::JSObject>. How can I squeeze the pointer out from it?

And I think we can leave with NULL pointers for those items which already have been freed (the number of possible names are fixed). Thus, can I just remove the removeCachedMethod at all?
