    Description

      FairCallQueue divides callQueue into multiple (4 by default) sub-queues, with each sub-queue corresponding to a different level of priority. The constructor for FairCallQueue takes the same parameter capacity as the default CallQueue implementation, and allocates all its sub-queues of size capacity. With 4 levels of priority (sub-queues) by default it results in the total callQueue size 4 times larger than it should be based on the configuration.
      capacity should be divided by the number of sub-queues at some place.
