+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.
