-%% TEST SUITE DESCRIPTION
-%%
-%% The test case function spawns two controlling processes: Starter and Receiver.
-%% Starter spawns a number of prio A and a number of prio B test processes. Each
-%% test process loops for a number of times, sends a report to the Receiver, then
-%% loops again. For each report, the Receiver increases a counter that corresponds
-%% to the priority of the sender. After a certain amount of time, the Receiver
-%% sends the collected data to the main test process and waits for the test case
-%% to terminate. From this data, it's possible to calculate the average run time
-%% relationship between the prio A and B test processes.
-%%
-%% Note that in order to be able to run tests with high or max prio test processes,
-%% the main test process and the Receiver needs to run at max prio, or they will
-%% be starved by the test processes. The controlling processes must not wait for
-%% messages from a normal (or low) prio process while max or high prio test processes
-%% are running (which happens e.g. if an io function is called).
