👉 Non-fusibility, in the context of computer science and software engineering, refers to a property that prevents two or more programs from executing simultaneously. This property is typically achieved by using synchronization mechanisms such as locks (mutexes) on shared resources or by using concurrency control structures like semaphores. Non-fusibility is crucial for ensuring thread safety, which means that the execution of one thread cannot interfere with the execution of another thread until a certain condition is met. It helps prevent race conditions and
