func checkIsolated() func checkIsolated() import _Concurrencyprotocol SerialExecutor : ExecutorA service that executes jobs.
func checkIsolated() Last resort “fallback” isolation check, called when the concurrency runtime is comparing executors e.g. during assumeIsolated() and is unable to prove serial equivalence between the expected (this object), and the current executor.
