I think lock-free is overrated for this use-case - we hold the lock for such a short amount of time. I think what we want is just a simpler spinlock - one that's faster than qlock for use-cases that are unfair anyway, like this one where even if you get the lock in a fair way, FIFO might be full and you won't be able to queue. Or find an API to add to FIFO in a fair way. -- MST
