I'm now leaning towards disabling persistent connections by default, and suggesting them in the deployment checklist.

They're useless in development, because the development server spawns a new thread for each request. Worse, if the GC doesn't jump into action fast enough, it's easy to exhaust the number of available connections, and the result is a failure to load some static files. Annoying and non-obvious.

Also, I'm not comfortable with the idea of breaking the sites of people who won't read the release notes, won't understand the consequences for them, or (gasp!) use runserver in production (some might be doing that in spite of our warnings).

<carljm> mYk: I think that's the right answer on #20215 (disabling by default).
