Subject: [PATCH] doc: improve worker pool example
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the worker pool example, the 'kWorkerFreedEvent' should be emitted
in case of error as well. After adding new worker in the error handler,
the pending tasks should be notified of an available worker.
