   * Based on Associate Mutexes with Data to Prevent Races, By Herb Sutter, May 13, 2010

   *
   * Make our mutex testable if it isn't already.
   *
   * Many mutex services (including boost::mutex) don't provide a way to ask,
   * "Do I already hold a lock on this mutex?"
   * Sometimes it is needed to know if a method like is_locked to be available.
   * This wrapper associates an arbitrary lockable type with a thread id that stores the ID of the thread that
   * currently holds the lockable. The thread id initially holds an invalid value that means no threads own the mutex.
   * When we acquire a lock, we set the thread id; and when we release a lock, we reset it back to its default no id state.
