I realized that we keep at least two copies of scripts.
This is the second place where we have script sources.

0 WTF::fastMalloc(unsigned long)
1 WTF::StringImpl::createUninitialized(unsigned int, unsigned short*&)
2 WTF::String::createUninitialized(unsigned int, unsigned short*&)
3 WebCore::StringTraits<WTF::String>::fromV8String(v8::Handle<v8::String>, int)
4 WTF::String WebCore::v8StringToWebCoreString<WTF::String>(v8::Handle<v8::String>, WebCore::ExternalMode)
5 WebCore::toWebCoreString(v8::Handle<v8::Value>)
6 WebCore::toWebCoreStringWithNullOrUndefinedCheck(v8::Handle<v8::Value>)
7 WebCore::ScriptDebugServer::dispatchDidParseSource(WebCore::ScriptDebugListener*, v8::Handle<v8::Object>)
8 WebCore::PageScriptDebugServer::addListener(WebCore::ScriptDebugListener*, WebCore::Page*)
9 WebCore::PageDebuggerAgent::startListeningScriptDebugServer()
10 WebCore::InspectorDebuggerAgent::enable()
11 WebCore::InspectorDebuggerAgent::enable(WTF::String*)
12 non-virtual thunk to WebCore::InspectorDebuggerAgent::enable(WTF::String*)
13 WebCore::InspectorBackendDispatcherImpl::Debugger_enable(long, WebCore::InspectorObject*)
14 WebCore::InspectorBackendDispatcherImpl::dispatch(WTF::String const&)
