Please test the attached patch, against kvm-17. This is subversion

Fails.
I notice that a lot of new code is related to pio. Seeing that it locks up when
the VPN starts using the network, I sprinkled some printk's around and have
discovered that we enter an long running (endless?) loop in kvm_run.
run->exit_reason is KVM_EXIT_IO, to the naive observer (me) it would appear that
an issue exists somewhere inside of handle_io().
The images that were reported to me as hanging seem to run fine, so
we're back to debugging this remotely. I now have more time so
hopefully we'll have a shorter loop.
Please apply the attached debug patch to kvm-18 so we can see what
handle_io() is looking at.
