fail-fast? not working

[rutchkiwi]

Hi. First of all, thank you for providing this awesome library, it has been a life saver for my team!

I can't seem to get the fail-fast? option to work when running tests from the repl like this:

(eftest/run-tests (eftest/find-tests "test")
                    {:multithread?    false
                     :report          eftest.report.pretty/report
                     :capture-output? true
                     :test-warn-time  500
                     :fail-fast?      true})

With this config, when a test fails it keeps going running all of them!

Getting this working would help me a lot, as running all my tests takes quite a long time when something funamental breaks (because so many errors are printed to the REPL).

Am I doing something wrong, or is this a real issue? I'm using [eftest "0.5.9"]

=== edit: Upgraded to 0.5.9 and the problem persists
