  <extension-point name="queues">
    <documentation>
      Defines the characteristics of work queues:
      <code>
        <queue id="myqueue">
          <name>My Queue</name>
          <maxThreads>4</maxThreads>
          <capacity>100</capacity>
          <clearCompletedAfterSeconds>300</clearCompletedAfterSeconds>
          <category>somecategory1</category>
          <category>somecategory2</category>
        </queue>
      </code>
      - id is the queue id.

      - name is the human-readable name.

      - maxThreads maximum number of worker threads (default 4).

      - capacity when specified make the queue bounded, the scheduling of
      new work is blocking when the queue is full (default unlimited).

      - clearCompletedAfterSeconds (default 3600) is the delay after which completed work
       may be automatically cleared from its queue. 0 means never.

      - category is a list of Work categories that this queue will receive.
      For event listeners work, the category is the listener name (or its simple class name).
