Is it really needed? Because Script is also a part of CacheResource right? Compiled code will be equivalent to DecodedData?

    if (!WebCore::memoryCache()->disabled()) {
        WebCore::memoryCache()->setDisabled(true);
        WebCore::memoryCache()->setDisabled(false);
    }

I guess. Above should purge the compiled code as well.

Sorry in case I'm wrong :)


Anyhow I will add all those things from MemoryPressureHandlerMac.mm
