Function twz_rt_futex_wait

pub fn twz_rt_futex_wait(
    word: &AtomicFutexWord,
    expected: FutexWord,
    timeout: Option<Duration>,
) -> bool

If the futex word pointed to by word is equal to expected, put the thread to sleep. This operation is atomic – the thread is enqueued on the sleep queue first, before the equality check. Returns false on timeout, true on all other cases.
