WU 267987175:
It currently has 8 different computers return their task (and one "timed out"), with one more working on it at the time of this post. I'm wondering what's special about this specific WU, at least, that makes it difficult to process. (Personally I don't see more than 3 or 4 computers work on a task before it gets validated in some way; and a 50/50 chance of just 3 computers with one of them being a "time out"/not returned in time.)
