That's because they all can be perfectly mitigated by setting a reasonable "speed" that matchs the host horsepower. Thinking about this again, I doubt that lengthening the duration with a hardcoded value benifits everyone; and before Alexandre's reply on old server/slow disks, I don't recall any report, because the coroutines would already yield often enough, when waiting for IO to complete. So I am not sure whether they're broken in practice. Fam
