Could we perhaps build something with an exception in this case, which
could be handled further up the object model?
"

I would say that an exception is not appropriate because the situation
would occur when there is no more buffer segments available because data
is still arriving (or is expected to arrive given the message size).
Maybe a "blocking" iterator (getNext()) would be appropriate, but I would
think that there are sometimes when you may not want to block...
