Right.

That's what I didn't want to do (at least, not without explanations from 
initial mail).
I added a link to this thread in the page, so this doesn't get lost.

+1

Right, I am confused too about the namings.
There is also the "message" naming used in the code to refer to an active 
object, and "active object" in the code is in fact used as container for 
asynchronous processing results...
A naming cleanup would make a lot of good, I think (I think of a lexicon in 
the wiki which would clearly state what is misnamed in the code, and the 
definition of each term).
