Do you mean the first big block TStep_ARKIMEX, right after
PetscFunctionBegin? Wow, if that works so it is a neat hack. I always
forget about this feature of Vec. Let me investigate it a little bit,
hopefully that is enough! Actually, is likely much better than
complicating the TSEvent API with extra flags.
