Steve Howell 42435db492 Add run_test helper for individual tests.
This run_test helper sets up a convention that allows
us to give really short tracebacks for errors, and
eventually we can have more control over running
individual tests.  (The latter goal has some
complications, since we often intentionally leak
setup in tests.)
