oc exec / rsh hangs for a long time on exit

[rhcarvalho]

After exiting an interactive shell session in a pod, the terminal hangs for several seconds before I can type anything back in the host.

[vagrant@openshiftdev origin]$ oc get pods
NAME            READY     STATUS    RESTARTS   AGE
mysql-3-9zgou   1/1       Running   0          3m
[vagrant@openshiftdev origin]$ time oc rsh mysql-3-9zgou
bash-4.2$ exit
real    0m29.163s
user    0m0.431s
sys     0m0.110s

Same for other pods, e.g., docker-registry.

I experiencing the same... After I exit from the /bin/bash session (oc exec -it foo /bin/bash) the terminal hangs for couple seconds.
