I've seen it, but I don't understand it.
Guess I have to rely on you to explain it. ;)

Mark Johnson had an interesting article in Linear Audio about using soft-recovery diodes, and showed (with lots of measurements) that even the best diodes cannot fully prevent secondary oscillations. He demonstrated that a simple CRC snubber across the secondary can fully suppress the oscillations even with the worst diodes.
