From my read, both implementation fulfills the\nrequirement but glibc claims that single futex does not provide the\nstronger ordering needed by its users hence switched to a rotational\nqueue, to fulfill the requirements mentioned in\nhttps://sourceware.org/bugzilla/show_bug.cgi?id\u003d13165. As in a single\nfutex, the lock acquisition do not happen in order and hence when a\nspurious wakeup happen, later waiters may \"steal\" the signal. However\nmusl\u0027s shared implementation and bionic\u0027s whole implementation and\nRust\u0027s std condvar still stick to a signal-futex+accounting data style.\n\nMusl\u0027s private condvar and this implementation are even stronger in the\nsense that not only the queue is decided as an atomic event, the mutex\nacquisition also happens in baton-passing style.\n\nOur implementation is different from musl in the sense that we have done\nsome spin attempts instead of always do futex syscall to requeue threads\n(with a new requeued state added). This gives a chance for the\nsignal/waiter to stay in fast path if the queue is really small. Based\non the microbenchmark, this implementation is generally more performant.\nWe also abuse the `RawMutex`\u0027s LOCKED state as \"waiting for its turn\".\n\nOne caveat we can see from the benchmark\n(https://github.com/SchrodingerZhu/condvar-benchmark) is that strict\nFIFO condvar is not that good if users are maintain the order on\nthemselves as in `turn_ring`, because many threads may just wake up\nfirst only see it is not its turn while blocking the real thread in\nturn. However, a semaphore or other synchronization primitives would be\nmore suitable in those cases. Even though in benchmark like\n`turn_ring/broadcast_stress` made this code perform badly (but still\nsimilar to musl anyway), they are not really the correct usage. In other\ncases, we are always close to the fastest while providing a stronger\nFIFO semantic.\n\nTODO in future commit:\n- support pthread cancellation.
