The code itself has a try/catch block wrapped around the QA tests,
with handlers for anticipated exceptions and a default uncaught
exception handler.  The fact that exception gr_signal is being thrown
is probably correct, but that fact that execution blows out the top of
the try/catch block instead of being caught is definitely not correct.
