Coverage works with subprocesses!
Starting coverage at startup didn't work.
Brought up internal coverage for cmdline to 100% in subprocess mode.
The amount of code to test the one line that makes the call to runner was over-the-top.  Especially since single-process python 2.7 _still_ wouldn't cover it.  It's pragma'd instead.
Switched to running internal coverage in subprocess mode for coveralls, instead of external coverage in single process mode.
