And then you have fabulous things like: https://git.reviewboard.kde.org/r/102145/ (OSX defines _POSIX_THREAD_PROCESS_SHARED but does not actually support it.) Seems not very well tested in any case. It might be worthwhile testing futexes on Linux though, they are specifically supported on any kind of shared memory (shm/mmap/fork/etc) and quite well tested.
