    This sounds like an ARP issue.  If the machine is being pounded
    to the point where it cannot ARP IP addresses, then packets will
    be queued both on the machine awaiting arp or on other machines
    trying to arp the one being pounded.
The ARP code only queues 1 packet pending resolution.  All the other
packets get dropped.  So when the ARP request is resolved, at most
one queued packet gets sent.
