Not sure about the ordering with the oneway; from what I understand
you would lose your synchronization at the point that the packet
gets delivered but it may not be fully processed before the call
returns in your server. I could imagine that the first packet could
be delivered but not fully processed, that task could be time-sliced
out by the scheduler, then the second packet could arrive and be
handled by a different ORB thread.<br>
<br>
You could run the ORB with a single-threaded model, but why not take
out the oneway in the interface and not have to worry about it?<br>
