> When using an async transport and async marshalling, an executor is used to process the marshalling task in a separate thread and the caller's thread is allowed to return immediately.
> When the executor's queue fills and the queue cannot accept any more tasks, it throws a {{RejectedExecutionException}}, causing a very bad user/developer experience.  A more correct approach to this is to catch the {{RejectedExecutionException}}, block and retry the task submission.
> The end result is that, in the degenerate case (when the executor queue is full) instead of throwing exceptions, those invocations will perform slightly slower.
