} Diagrammed:
} 
}   Event #1 starts processing.
}     Event #1 creates $Bubba.
}     Event #1 calls $Bubba.haircolour("brown")
}     Event #1 sets up Event #2 in its C&C success list.
}   Event #1 (eventually) C&C's successfully.
}     $Bubba is committed with brown hair.
} 
}   Event #2 ripens and starts processing.
}     Event #1 calls $Bubba.haircolour("white")
}   Event #2 (eventually) C&C's successfully.
}     $Bubba is committed with white hair.
} 
} The basic idea is that an event can define a number of other events which are
} to be logged if the current event suceeds or fails.

Does it done automatically or does the coder have to explicitly write something
like:
	if Event_Successful then ...


So, the stuff that has to be buffered until the successful C&C is:
  - I/O (outbound)
  - Starting of new events

Did I miss any?
(I think that no special treatment is needed for creating/destroying objects,
since they may be created in the cache and written tto tthe DB along with the
other C&C changes).


Have fun,
Alex.
