thanks again Guenter,
the fear is of having an output message which is passed from my object to a couple of targets, where the first target would then pass some data back to my object, thus overriding the buffer. I would like to safeguard against a possibility of passing a message from an overwritten buffer to the other destination.
Of course, blocking reentrant calls (``doing nothing''), is one of the options...

I see, if I understand it right the fear is you get called again while your old message might still be useful in some context ? i am not sure if this can happen within pd, because the messages are delivered directly from within the method, and recursion on this level isn't possible ?
