Subject: [PATCH] Wait for udev events to be handled after removing veth
As per http://www.redhat.com/archives/libvir-list/2013-July/msg01279.html,
wait for udev events to be handled after removing a virtual NIC.
Any udev rule associated to NIC destroy could happen to run with a new
device with the same name that is being created.
