 mutex, and two of the threads lock two of the mutexes in different orders. For
 example, consider mutexes `mu1` and `mu2`, and threads T1 and T2, executing:

 When the mutexes involved in a locking sequence are known at compile-time, then
 avoiding deadlocks is “merely” a matter of arranging the lock
