@GwtIncompatible
final class ListenerCallQueue<L>
extends java.lang.Object
implements java.lang.Runnable
```
A special purpose queue/executor that executes listener callbacks serially on a configured executor. Each callback task can be enqueued and executed as separate phases.
This class is very similar to SerializingExecutor with the exception that tasks can be enqueued without necessarily executing immediately.
