And if it becomes a problem we might in a future version be able to add 
something like a 'messagepostfailed' event that is fired on the sending 
port in case a message failed to reach its target for one reason or another.

However before we add any such mechanisms I think we should gain some 
implementation experience. It has been raised that even the current spec 
might be very hard to implement in a cross-process situation and so we 
should be careful to add more complexity.
