Sounds like a good plan since this probably is a nice way to make stupid apps doing stupid things sit up and take notice, and maybe the authors will then go so far as fixing up a few more things that are hurting them once they actually recognize that something is weird due to overly bad performance. Why go to great lengths to support stupid apps when there are still so many things which could be done to help well-behaving ones? ;) Andreas Mohr - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
