+/**
+ * Helper to verify that the event loop was spun.  As long as this is dispatched
+ * prior to a call to Close()/SpinningSynchronousClose() we are guaranteed this
+ * will be run if the event loop is spun to perform a close.  This is because
+ * SpinningSynchronousClose must spin the event loop to realize the close
+ * completed and our runnable will already be enqueued and therefore run before
+ * the AsyncCloseConnection's callback.  Note that this invariant may be
+ * violated if our runnables end up in different queues thanks to Quantum
+ * changes, so this test may need to be updated if the close dispatch changes.
