Small spec simplification
Version 1.0.0b3
Version 0.9.3

Yes, I know version 1.0.0b3 is already out. But the Mailman bundler is
operated by Buildout, and it frowns on beta version (as it should). So
I'm releasing the same code on version 0.9.3.
Fix running unittests when a mailman daemon is active
Bump version
Merge branch 'release-1.0'
