I think I found a Mac kernel bug?
I've edited 'he' to 'she' in the two otherwise fine comments that made this mistake (<a href="https://news.ycombinator.com/item?id=16251566" rel="nofollow">https://news.ycombinator.com/item?id=16251566</a> and <a href="https://news.ycombinator.com/item?id=16251562" rel="nofollow">https://news.ycombinator.com/item?id=16251562</a>) and grouped several empty replies and one lame off-topic subthread under this one. It's rare that we do something like this (and I've emailed the author), but it seems fairer than to penalize their original posts, which were otherwise informative and on topic.
