The idea is to do it sooner rather than later. If you'll recall from 
that earlier email, there was a longstanding issue that I wanted to see 
progress on, related to Oracle TZUpdater. When I asked about that I got 
email back saying that the relevant person at Oracle was on vacation. 
They should be back so I'll ping Oracle now. If I don't get a response 
soon, we can go ahead and issue a new release and deal with any problems 
in a later release.
