again, the question is, what for did you need it exactly ? what feature of the single-buffer do you need ?
mostly for non-realtime hand knitted videoprocessing, kind of pixeldrawing. sometimes drawing traces could be very useful, at least for me. so i can draw one frame without ruffle and put say 50.000.000 rectangles per frame. additionally i can clear gemwin whenever i want.
here are some examples, if you are interested:
