> 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.
