In order to test weave's container network impact, on the limit, I
started 200 "sleep 7200" pods with the busybox image, with "hostNetwork:
true" to disable container networking.
This time, I was able to run 200 replicas, but I was unable to go to
over 200 pods, I tried the grow the replicas count to 300 and just got
100 pods in a ContainerCreating state, and the same logs.
