> If resource localization fails then resource remains in memory and is
> 1) Either cleaned up when next time cache cleanup runs and there is space crunch. (If
sufficient space in cache is available then it will remain in memory).
> 2) reused if LocalizationRequest comes again for the same resource.
> I think when resource localization fails then that event should be sent to LocalResourceTracker
which will then remove it from its cache.
