In the 'Testing accuracy of equeue semaphore' test case result is printed out in each loop iteration.
Since debug prints should not exist in the final test version I suggest to print information only in case of failure.
Additionally time needed to print single info is equal to ~25 ms (K64F/GCC_ARM). The while loop is designed to execute until 20000 ms elapses, so this print has also impact on number of times the loop is executed (number of semaphore accuracy checks).
A units mistake led to passing 20000 seconds instead of 20000 milliseconds
to greentea. The would cause the test to spin for 6 hours if it got stuck
anywhere.
