A normal message is between two concrete vobjects. An update message is
sent from a concrete vobject to update its replicas. For example, a
property sending out a change notification. It's not a "normal"
message, because the actual C++ object the message is delivered to is
not a concrete Vob
I'm sure if I spend more time tracing the code i could figure this out
myself, but I'm in a lazy mood...
What's the difference in the way Messages and UpdateMessages are handled by
the VOS library? Why can't everything be treated as a plain Message?
