ACK -- I can now reproduce with both "nmap -sT" and "nmap -sU"
from dom1 to dom0.

Doing the same from dom0 to dom1 works fine, as does going from
dom1 to an external machine.

What's surprising is that I can run both a tcp and udp blaster in
both directions between dom0 and dom1 without triggering the bug.
It must be something specific to incoming connections, which is
quite a surprise as there should be nothing xen specific about
this. I wander if we're provoking a latent linux bug?

Now we can reproduce it should be possible to work out what's
going on...
