Well, unfortunately it is also wrong thing to do :-(.

Imagine for a moment that we solve time-warp somehow. Any other problems? [I'd really like to get "is user idle" solved, but it really should not be in kernel unless it _has_ to. And time-warp probably causes problems not only for your daemon.] Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
