I don't want to reduce test coverage either. I think the most painless
way to improve matters would just be to work harder on running tests in
parallel. I think most devs these days do most of their work on 4- or
8-core machines, yet almost everything except the core regression tests
is depressingly serial. I think we could likely get a 2x or better
reduction in total runtime without too much work just by attacking that.
