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().
