- The kubelet plugin manager now properly handles plugin registration failures by removing failed plugins from the actual state and retrying with exponential backoff (initial delay 500ms, doubling each failure up to ~2 minutes maximum) to protect against broken plugins causing denial of service while still allowing recovery from transient failures.

Unfortunately, there is a much rarer second possible failure mode: the replication controller gets renamed to the old name, but there is a duplicated set of pods in the cluster. kubectl will not report an error since it thinks its job is done.
