> So, are you saying that we'd just pass INT_MAX as optimal number of threads? Even if that works, it sounds like an abuse.

hmmmm, not exactly. I would rather say that the optimal number would depend on the input, like we want to start a job for each 5000 pixels (don't think every pixel should have an own thread...), so the optimal would be round_up(width * height / 5000)

> I think that using parallelism more would be a good topic for WebKit contributor meeting discussion this month.

Absolutely true. Unfortunately we can't be there in person. I hope we could follow you somehow, like mails, or something...
