Hi Brian et al,

I'd prefer to wait with an actual in-depth look until the
theory-of-operation docs are in.

As an aside, what's the testing matrix that this code went through so far?
Pitfalls in my head would be concurrent access from multiple clients, rdbm's
(sqlite, mysql MyIsam, InnoDB, etc), odd sources with *very* long file

> Bzr.testRetry) that have been failing on my laptop for six months.
> The next steps are:
>  * write up docs, theory-of-operation material
>  * explain the importance of "buildbot upgrade-master" in NEWS
>  * make it easier to use MySQL instead of the default sqlite
>  * add a few config knobs to enable mozilla's multiple-master-one-DB
>   scheme
>  * clean up the Loop triggers (remove the every-30-second poll)
> I'll be working on these slowly over the next few weeks. In the

> Without running that command, you won't get a database and the new code

> will of course create a DB too).
