I'don't like adding a couple seconds of test runtime for the benefit of
very slow platforms.

The second pg_ctl start doesn't seem to test something very
interesting. I'm inclined to just remove it. I'm not caffeinated
sufficiently, but afaics that ought to sidestep the issue as stop
doesn't depend on the slop time?

Sounds like an actual production hazard too.
