Bug Description

can you please add an option on exiting upon first failure? (ie nosetest --stop)

thanks

testr can't support --stop in the same way as nose because it's a meta-runner, not a runner. However subunit.run, like testtools.run, like unittest supports --failfast (or -f).

So
testr run -- -f
will run single-worker and cause that worker to stop one a single failure occurs.

I'm very open to the idea of cancelling other workers once a failure is detected in parallel mode, if someone wants to work on a patch.
