> {{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.
