Labels on nodes can be used in conjunction with node selectors on pods to control scheduling,
e.g. to constrain a pod to only be eligible to run on a subset of the nodes.
Marking a node as unscheduleable will prevent new pods from being scheduled to that
Marking a node as unschedulable will prevent new pods from being scheduled to that
node, but will not affect any existing pods on the node. This is useful as a
preparatory step before a node reboot, etc. For example, to mark a node

The `kubelet` currently polls `cAdvisor` to collect memory usage stats at a regular interval. If memory usage
increases within that window rapidly, the `kubelet` may not observe `MemoryPressure` fast enough, and the `OOMKiller`
will still be invoked. We intend to integrate with the `memcg` notification API in a future release to reduce this
latency, and instead have the kernel tell us when a threshold has been crossed immmediately.

If you are not trying to achieve extreme utilization, but a sensible measure of overcommit, a viable workaround for
this issue is to set eviction thresholds at approximately 75% capacity. This increases the ability of this feature
