I'm concerned that this will be difficult to code correctly,
specifically the "automagic bug filing". The first failure is easy, but
what if I thought I fixed it, but hadn't. It files a new bug. Rinse,
repeat, bloat bugzilla and/or spend time chasing down dupes.

I could be wrong about that though.

The very specific logic path is this:

1. A build is submitted.
2. Primary architectures run. If any primary architecture fails, it
stops.
3. When all primary architectures pass, then the build is sent to all
secondary architectures.
4. Each secondary architecture runs to completion. Failures by any
secondary architecture do not affect other secondary architectures.
5. Secondary architectures which failed make a lot of noise. (This is
where automagic bug filing occurs, emailing architecture teams, etc).
