Yep, that sounds good.

I have too much going on. I need to cut the number of things and spend less time on them. It's easy for little things, but large reviews are particularly hard to slot in my schedule -- risk of regression, a lot of effort put in, so a minimal ammount of care and attention is necessary. But I can't afford to micro manage / nitpick anymore Jose _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
