The method should finally be correct. I ran into the race while testing #15871, where another thread can finish so fast that it races with the attempt to wait. With this patch, I can't reproduce the bug anymore. |

I don't always enqueue the calling fiber in the wait list, to avoid a race condition, but always suspend it... which leads to the race condition never resuming the fiber 🤦
