Some caches(PatchCache, TextureCache, PathCache) for HWUI uses deferred removal for their cache entries even though actual resource objects are immediately freed by ResourceCache. For this reason, the uniqueness of a resource address in the caches is not guaranteed in specific cases. (Because malloc() can return the same address when malloc() and free() called very frequently.) So it can be possible the cache have two cache entries for two different resources but the same memory address. (Of course one of the resources is already freed.) It also can be possible mGarbage vector in PatchCache has duplicated addresses and this can lead to duplicated free blocks in the free block list and graphics corruption. (Deferred removal was implmeneted based on an assumption of unique resource addresses.) So this patch makes sure resource objects are freed after the resources are removed from the caches to guarantee the uniqueness of a resource address and prevent graphics corruption.
