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 ;-)
