I certainly didn't intend for them to be independent, and I don't
think they should be. I think it should be a hierarchy - as it is
currently. I think it's a bad idea to introduce the notational
overhead of having to pass through two integers rather than one
everywhere, and a worse idea to encourage people to think of the
wait_event_type and wait_event are related any way other than
hierarchically.

Hmm, I could live with that, if other people like it.

Agreed; or perhaps it could even be waiting for another regular backend.
