Construct recursive_mutex
Constructs a recursive_mutex object.
The object is in an unlocked state.
recursive_mutex objects cannot be copied/moved (both the copy constructor and assignment operator are deleted for this type).
Data races
The construction of recursive_mutex is not atomic itself: Accessing the object while being constructed may initiate a data race.
Exception safety
No-throw guarantee: never throws exceptions.
