Kernel events without kevents

Since it doesn't see any use in the mutex API that everyone uses, it's not surprising... Code that's not used tends to rot.

Too bad, I would like that. I'll stay with my "pipes as semaphores" trick in the meantime...

You're right. Apparently it's "unfixably racy" and will disappear in June 2007.
