Detailed Description

Class implementing a Mutex. Mutexes are used to lock data structures to ensure that only a single thread of execution can access them at the same time.

Copy semantics

When copied, the receiving object does not receive any state from the object being copied, i.e. an entirely new mutex is created. This is consistent with expectations if a mutex is used as a member variable to lock the other member variables of a class: in that case, the mutex of the copied-to object should only guard the members of the copied-to object, not the members of both the copied-to and copied-from object.
