```
public interface CriticalComponent
```
A Critical component enters and leaves a critical state. You update a long every time you enter a critical path you update a different long with a System.nanoTime every time you leave that path. If the enterCritical > leaveCritical at any point, then you need to measure the timeout. if the system stops responding, then you have something irresponsive at the system.
