Public bug reported:

To reproduce:

http://paste.openstack.org/show/54794/

I used Ctrl-D (EOF) on a new line to end input, but it did not respond.

The netwrap process was still running in the dom0 after I Ctrl-C'd.

```
[root@xen ~]# ps aux  | grep netwrap
root      9987  0.0  0.6   8664  4840 ?        Ss   03:27   0:00 python /etc/xapi.d/plugins/netwrap <methodCall><methodName>run_command</methodName><params><param><value>OpaqueRef:c4567826-fa48-c815-2de8-dbb97bad01cd</value></param><param><value><struct><member><name>cmd</name><value>[&quot;ovs-ofctl&quot;, &quot;add-flows&quot;, &quot;fake-br&quot;, &quot;-&quot;]</value></member></struct></value></param></params></methodCall>

[root@xen ~]# kill 9987
```

I originally encountered this bug working on blueprint ovs-firewall-
driver by invoking
neutron/agent/linux/ovs_lib.py:OvsBridge.defer_apply_off. I have a
feasible workaround for now by avoiding use of stdin.
