Description Meng Bo 2015-08-26 09:07:43 UTC 
Description of problem:
Login to the container via oc exec with interactive mode, and when trying to exit from the container it will take a long while. (Over 20 seconds)

Version-Release number of selected component (if applicable):
oc v1.0.5-25-ga16d9c8
kubernetes v1.1.0-alpha.0-1605-g44c91b1


How reproducible:
always

Steps to Reproduce:
1. Create pod which can be logged in with bash
$ oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/authorization/scc/pod_requests_nothing.json
2. Login to the pod
$ oc exec pod1 -it /bin/bash
3. Do anything in the container, eg `ls`
4. Exit the container 
$ exit

Actual results:
It will take over 20 seconds to exit the container.

Expected results:
Should not hang there so long.

Additional info:
Use `oc rsh` to login to container will also have this problem.
And both `docker exec` and `nsenter` can exit from the container immediately.
