This might indicate a high-memory bug in the net driver(s). The TCP re-send
theory makes no sense -- the decision to re-send is always made by the TCP
protocol stack in the domU. dom0 itself will never decide to re-send.

How much memory does your test system have? Are you running 64-bit Xen, PAE
Xen, or non-PAE 32-bit Xen?
