You're right on the second point and the third, though I reckon the fragmentation isn't appreciably worse than in a regular wrap-around circular buffer. Same goes for the first point. I'm keen to see examples where bip buffers exhibit particular issues relative to circular/ring buffers, however, and if you've got any then please send them along. The chief use-case for my bip buffer implementation is using a shared memory segment for inter-process communication, and adding mmap() for address mirroring on top of that just seems like a can of worms I'm not particularly interested in opening.
