If you're so inclined, you can check out the ring that is being kicked
around in the syslets patches.  The main criteria there is that there
isn't a syscall to build up and initialize kernel state for the ring.
It means we have to play some games to serialize the two blocking stores
that make up event insertion, but there are some things we could do there.
