+/** 
+ * testDyingUpdateQueueProcess
+ * This process is an example of a process using an updateQueue.
+ * The datums updated by this process behave badly and block the update loop
+ * by sleeping. If you #define UPDATE_QUEUE_DEBUG, you will see the updateQueue
+ * killing off its worker processes and spawning new ones to work around slow 
+ * updates. This means that if you have a code path that sleeps for a long time
+ * in mob.Life once in a blue moon, the mob update loop will not hang.
