No need to apologize, we all need holidays.

Ok, thanks for the further description. It would help though, if the 
unconsumed_event method was documented explicitly in the docs. I think I 
missed it as it's not presented as a link - in the state_machine reference 
there's only a link to the description of process_event() effects in the 
line above.
