Still haven't found an answer. :/ It's something to do with mds running amok. Even after I have disabled Spotlight indexing my entire HD, whenever Time Machine launches for a backup, mds does too. I've caught it stealing 30GB virtual memory and nearly 3GB of real memory. Drives everything to a crawl. Tried everything. No luck. Just riding it out until new Haswell rMPB comes out I think.
