 * Unit test for [FastFallbackExchangeFinder] implementation details.

 * This test uses [TaskFaker] to deterministically test racy code. Each function in this test has

 *
 *  * prepare a set of plans, each with a predictable connect delay
 *  * attempt to find a connection

* Dodać nową funkcję.
    * Upewnij się, że dodajesz testy.
    * Upewnij się, że dodajesz dokumentację, jeśli jest to istotne.

## Pomóż w utrzymaniu FastAPI

Pomóż mi utrzymać **FastAPI**! 🤓

Jest wiele pracy do zrobienia, a w większości przypadków **TY** możesz to zrobić.

Główne zadania, które możesz wykonać teraz to:

 *  **OkHttpClient is now stateless.** In the 2.x API `OkHttpClient` had getters
    and setters. Internally each request was forced to make its own complete
    snapshot of the `OkHttpClient` instance to defend against racy configuration
    changes. In 3.x, `OkHttpClient` is now stateless and has a builder. Note
    that this class is not strictly immutable as it has stateful members like
    the connection pool and cache.

* Fixed ingress issue with CDK and pre-1.9 versions of kubernetes. ([#61859](https://github.com/kubernetes/kubernetes/pull/61859), [@hyperbolic2346](https://github.com/hyperbolic2346))
* Fixed racy panics when using fake watches with ObjectTracker ([#61195](https://github.com/kubernetes/kubernetes/pull/61195), [@grantr](https://github.com/grantr))

      return true
    }

    if (failedConnection != null) {
      val retryRoute = retryRoute(failedConnection)
      if (retryRoute != null) {
        // Lock in the route because retryRoute() is racy and we don't want to call it twice.
        nextRouteToTry = retryRoute
        return true
      }
    }

    // If we have a routes left, use 'em.
    if (routeSelection?.hasNext() == true) return true

- Ensure that client-go's EventBroadcaster is safe (non-racy) during shutdown. ([#95664](https://github.com/kubernetes/kubernetes/pull/95664), [@DirectXMan12](https://github.com/DirectXMan12)) [SIG API Machinery]
