      | This is the default configuration of the runnable-manager. More
      | indepth information can be found at
      | http://gee.cs.oswego.edu/dl/classes/EDU/oswego/cs/dl/util/concurrent/PooledExecutor.html
      | The following elements can be used:
      |
      | thread-factory:        specifies the fully qualified class name of an
      |                        org.apache.cocoon.components.thread.ThreadFactory
      |                        implementation. It is responsible to create Thread
      |                        classes.
      | thread-pools:          container element for thread-pool elements.
      | name:                  required name of the pool.
      | priority:              optional priority all threads of the pool will
      |                        have (the ThreadFactory will be set to this
      |                        priority).The possible values  are:
      |                          MIN:  corresponds to Thread#MIN_PRIORITY
      |                          NORM: corresponds to Thread#NORM_PRIORITY (default)
      |                          MAX:  corresponds to Thread#MAX_PRIORITY
      | daemon:                whether newly created Threads should run in
      |                        daemon mode or not. Default to false.
      | queue-size:            optional size of a queue to hold Runnables if the
      |                        pool is full. Possible values are:
      |                          less than 0:    unbounded (default)
      |                          equal to 0:     no queue at all
      |                          greater than 0: size of the queue
      | max-pool-size:         optional maximum number of threads in the pool.
      |                        Defaults to 5.
      |                        NOTE: if a queue is specified (queue-sie != 0)
      |                              this value will be ignored.
      | min-pool-size:         optional minimum number of threads in the pool.
      |                        Defaults to 5.
      |                        NOTE: if a queue has been specified (queue-sie != 0)
      |                              this value will be used as the maximum of
      |                              thread running concurrently.
      | keep-alive-time-ms:    The time in ms an idle thread should keep alive
      |                        before it might get garbage collected. This
      |                        defaults to 60000 ms.
      | block-policy;          The policy to be used if all resources (thread in
      |                        the pool and slots in the queue) are exhausted.
      |                        Possible values are:
      |                          ABORT:         Throw a RuntimeException
      |                          DISCARD:       Throw away the current request
      |                                         and return.
      |                          DISCARDOLDEST: Throw away the oldest request
      |                                         and return.
      |                          RUN (default): The thread making the execute
      |                                         request runs the task itself.
      |                                         This policy helps guard against
      |                                         lockup.
      |                          WAIT:          Wait until a thread becomes
      |                                         available. This policy should, in
      |                                         general, not be used if the
      |                                         minimum number of threads is zero,
      |                                         in which case a thread may never
      |                                         become available.
      | shutdown-graceful:     Terminate thread pool after processing all
      |                        Runnables currently in queue. Any Runnable entered
      |                        after this point will be discarded. A shut down
      |                        pool cannot be restarted. This also means that a
      |                        pool will need keep-alive-time-ms to terminate.
      |                        The default value not to shutdown graceful.
      | shutdown-wait-time-ms: The time in ms to wait before issuing an
      |                        immediate shutdown after a graceful shutdown
      |                        has been requested.
