ganeshmurthy commented on issue #514: DISPATCH-1349 qd_buffer_list_clone is
wasting dst buffers available capacity
URL: https://github.com/apache/qpid-dispatch/pull/514#issuecomment-497795391
My next observation is that the msg->ma_to_override, msg->ma_trace and
msg->ma_ingress always has at least one buffer associated with them even in
the one router single sender, single receiver case.
If we have only one router and the sender is not sending in any annotations
and there is only one receiver on the same standalone router, why are these
buffer populated in the first place and since they are populated, we are
performing the extra overhead of copying them. If a message visits only one
router in its lifetime, this seems like a waste of time
