Running method while destroying the object

Question

A few days ago my friend told me about the situation, they had in their project. Someone decided, that it would be good to destroy the object of NotVerySafeClass

Answer 1

Why not make use of a mutex / semaphore ? At the beginning of any method the mutex is locked, and the destructor wait until the mutex is unlocked. It's a fix, not a solution. Maybe you should change the design of a part of your application.
