[ovs-dev] OVS and namespaces

When Quantum is using OVS and namespaces there are problems when 
namespace is being deleted. More specifically this is when a default 
gateway is assigned to an interface that is used by the OVS. A simple 
way of reproducing this is:

sudo ip netns exec<name>  ip route del ...
sudo ip netns exec<name>  ovs-vsctl del-port...

 From this moment on one is not able to access the namespace. The 
problem does not occur when the traditional linux bridges are used.

Has anyone encountered this before?
