Meta: what a strange bug? I see multiple of this post on the front page, some with slightly different vote counts. Will this comment appear in all of them? Yes, it does.
There are a few posts doing this, repeating on the listings.
Yup, just noticed that on the last refresh. I bet there are hundreds of us clicking refresh very often right now, to see this. I am sure that is helping :)
I wonder if this is related to the recent refactor, multi-core support, etc.
