I can provision a Python 3 buildbot 0.9 worker upon request if that
would help ease/verify/test the migration.

The FreeBSD buildbot port/package was updated to 0.9 a while ago, and
given the lack of backward compatibility (with a 0.8 master), I've had
to hold off on upgrades. Getting the 0.9 migration done sooner would for
me result in less management and support overhead than keeping it as is,
effectively an unsupported state downstream.

I would also be happy to switch the existing 2 'stable' FreeBSD (0.8)
workers over to 0.9 and a 0.9 server at any time, but would want to
ensure that doing so wouldn't:

- reduce branch/build-type coverage the 0.8 server config provides
- reduce visibility of their statuses to developers. (see them go and
stay red)
