Sure, I was in fact implying its not the end of the world,
although it will be interesting to see the impact on different
(non pathological) workloads, even if it only affects a single
waiter. Also, technically this issue can also affect rwsems if
only using writers, but that's obviously pretty idiotic, so I
wouldn't worry about it.

Thanks,
