There were multiple issues with flow control when exceptions occur. Fixed these by ditching the reliance on the exception thrown interrupt and introduce an exception handler interrupt, which indicates control is about to pass to a catch clause. This gives us much better insight into how execution is flowing and how we might need to adjust an in-flight stepping operation.
