This is mostly needed for auto-optimization/iracepy#22 because error from the user defined function would not propagate from a python function targetRunnerParallel to the embedded R instance. If I raise an error, rpy2 will just swallow the error and return NULL instead. I am not sure if this is a feature or a bug. But in any case, we need to stop irace at that point otherwise it will just go on and fail somewhere else, alerting the user of an "internal bug" and taking down the python interpreter with it due to auto-optimization/iracepy#27.
