It's the implementation used by libpd for passing messages between the audio thread to the various hooks. It is also used in the libpd Obj-C PdAudioUnit for buffering samples sample rate conversion is happening and the buffer size is inconsistent. If it was broken in some way, we would have heard about it over the last 10+ years or so. I trust the guy who wrote it (Peter Brinkmann) but it is admittedly older code now and I only updated to C atomics in a cursory manner via the macros. If y'all have thoughts/suggestions on improvement, please open an issue (or better a PR) on the libpd Github repo.
