Description of problem:
When creating a new deployment or scaling/refreshing an existing one, deployments take a very long time and may timeout. Symptoms also include pods being stuck in a 'Pending' or 'Terminating' state for a long time and replication controllers not reflecting the current/desired number of pods correctly, for example:
$ oc get pods
NAME READY STATUS RESTARTS AGE
httpd-5-j24x4 0/1 Terminating 0 15m
httpd-8-deploy 0/1 Error 0 12m
httpd-8-rlpzs 1/1 Running 0 12m
httpd-8-sgdcs 1/1 Running 0 5m
$ oc get rc
NAME DESIRED CURRENT READY AGE
httpd-7 1 1 1 21m
httpd-8 0 0 0 12m
$ oc get dc
NAME REVISION DESIRED CURRENT TRIGGERED BY
httpd 8 1 0 config,image(httpd:2.4)
This appears to be accompanied with slow etcd performance and consistent api errors related to pod listings.

Steps to Reproduce:
1. Create a new deployment or scale/refresh an existing one
Deployments take an excessively long time to process and either remain in an incorrect state or fail.
Deployments would work as expected.
