Fine, but we can wait till 2.6.38 for that. For now we have a manual config option. I'm not changing it until I have 4.5.2 in my distcc farm and testing it out.
If things turn out fine, we can have > 4.5.2 || run check option. Or just stick with 4.5.2. But we can debate this later (or at KS if you want ;-)
