groovyx.gpars.util.DefaultMessageQueue

All Implemented Interfaces and Traits:

MessageQueue
```
@java.lang.SuppressWarnings({"SynchronizedMethod", "ArithmeticOnVolatileField", "FieldAccessedSynchronizedAndUnsynchronized"})
public final class DefaultMessageQueue
extends java.lang.Object
```
An implementation of the message queue for actor and agent messaging. It leverages the fact that in any moment there's only one reading thread accessing the queue and that potential read thread swap at the actor or agent thread pool synchronizes thread memory.
We also count on writers not to call the isEmpty() method
