Review comment:
Yes, it's changing semantics (as I had written in commit message). I
have not found a good reason why it's not always exited and it makes things
easier especially since this method can now be used to process priority events.
Btw I think it also changes semantics for all event that are not handled at
all, but I'm not sure which events survive at this point (Superstep?).
