Description of problem:
If the deleteion of a namespace fails (for example run  quantum-netns-cleanup --force), then one is unable to access the namsepace from that moment on:

[root@dhcp-4-126 ~]# ip netns exec qdhcp-412dc916-6975-4956-9be0-0dac739657e0 ip link
seting the network namespace failed: Invalid argument


Version-Release number of selected component (if applicable):
Linux dhcp-4-126.tlv.redhat.com 2.6.32-358.6.2.openstack.el6.x86_64 #1 SMP Wed May 29 19:20:22 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:
Every time

Actual results:

Can you somehow reproduce that without the use of quantum? I can't get the namespace deletion to fail.
