   refs: https://github.com/apache/incubator-pekko/issues/661
   
   The Current VirtualThrad in JDK 21 making use of the `externalSubmit`
   ```java
   if (s == YIELDING) {   // Thread.yield
               setState(RUNNABLE);
   
               // notify JVMTI that unmount has completed, thread is runnable
               notifyJvmtiUnmount(/*hide*/false);
   
               // external submit if there are no tasks in the local task queue
               if (currentThread() instanceof CarrierThread ct && ct.getQueuedTaskCount() == 0) {
                   externalSubmitRunContinuation(ct.getPool());
               } else {
                   submitRunContinuation();
               }
           }
   ```
   
   I think this change will affect the performance.
