At FoundationDB we use this technique extensively (we call it "buggification"), along with deterministic simulation to make the results debuggable. Amusingly (and embarrassingly), some of our early alpha and beta releases shipped with buggification accidentally enabled! It hurt performance a little, but didn't break the database for anyone that we know of.
