I know this is how it's done now. But it is not where it has to end.
IMO we have to get to a solution where new events are posted to the ring
buffer asynchronously, i.e., without a thread calling kevent_wait. And
then you need the extra parameter and verification. Even if it's today
not needed we have to future-proof the interface since it cannot be
changed once in use.
