While I was working on some trigger related stuff today, I saw a bunch of fedmsg-triggered events for builds that we really don't want to be triggering jobs over. I didn't see what the unwanted builds were being tagged as (some were fc18 builds for a single non-noarch arch) but I suspect that we'll want to filter the messages for tags that we actually want to watch (fXX-updates-pending, fXX-updates-testing-pending etc.)
