 * <p>The API of this class is designed to make it easy to achieve the following properties
 *
 * <ul>
 *   <li>Multiple events for the same listener are never dispatched concurrently.
 *   <li>Events for the different listeners are dispatched concurrently.
 *   <li>All events for a given listener dispatch on the provided executor.
 *   <li>It is easy for the user to ensure that listeners are never invoked while holding locks.

So we have a dedicated thread for every socket that just reads frames and dispatches them.

The reader thread must never run application-layer code. Otherwise one slow stream can hold up the entire connection.

## Dependencies

### Added
_Nothing has changed._

### Changed
- k8s.io/kube-openapi: 9528897 → 2043435

- Executed API calls dispatched during pod scheduling asynchronously if the `SchedulerAsyncAPICalls` feature gate was enabled.

- Two changes to the `/debug/api_priority_and_fairness/dump_priority_levels` endpoint of API Priority and Fairness: added total number of dispatched, timed-out, rejected and cancelled requests; output now sorted by `PriorityLevelName`.
