The main thread acquires locks A and B, then it creates three higher-priority threads.

The first two of these threads block acquiring one of the locks and thus donate their priority to the main thread. The main thread releases the locks in turn and relinquishes its donated priorities, allowing the third thread to run.

In this test, the main thread releases the locks in a different order compared to priority-donate-multiple.c.
