  3.  Reproduce steps

  * I made a docker container image which has control application like quagga (has zebra and ospf deamons).
  * then glanced it and launch the container from controller node.
  * when container is up , i launch zebra and ospf from container using following command from container terminal:
      for zebra:
     sudo /usr/local/quagga/sbin/zebra  -u root -g root -i /usr/local/quagga/etc/zebra.pid
      for ospf:
     /usr/local/quagga/sbin/ospfd -u root -g root -i /usr/loc/usr/local/quagga/etc/ospfd.pid
  * then if immediately i want to attach vtysh terminal to ospf deamon , it could not connect immediately it will take 3 mins. time to  attach.
  *then on debugging i found that a linux read() from file halts ospf deamon.

  
  Expected result:
  * vtysh should connect immediately to ospf 
  Actual result:
  * it takes around 3 mins. to connect.

  Remark:
  when i launch container from my VM and NOT via openstack i get the desired result, but not with container launched with openstack.( that's the reason i am reporting bug here).
