+/**
+ * @class TAO_EC_Priority_Dispatching
+ *
+ * @brief Dispatching strategy that minimizes priority inversion.
+ *
+ * This strategy uses multiple queues, each serviced by a thread
+ * at different priority.  This minimizes priority inversion
+ * because the consumers at higher priority are serviced before
+ * consumers at lower priority.
+ * It is more flexible than using the supplier thread to dispatch
+ * because it allows high-priority suppliers to push events to
+ * low-priority consumers (and vice-versa).
+ * It also isolates the supplier threads from the time spent on
+ * upcalls to the consumer objects, making the system easier to
+ * analyze and schedule.
