I'd prefer the version I posted to you under separate CL to this.  Partly
because I think it does 95% the same thing, but partly because I feel like this
is kind of arbitrary to be bundled into your CL (I want to have a clear idea of
where the change came from in two years when it's breaking someone's sql code
:-).

Agreed. I'll wait until you land yours and rebase once that happens.

   const base::TimeDelta kBusyTimeout =
     base::TimeDelta::FromSeconds(kBusyTimeoutSeconds);
