In this section we want to examine the connection between inheritance-based designs and the cost of constructors and destructors. We drive this discussion with a practical example: the implementation of thread synchronization constructs.[1] In multithreaded applications, you often need to provide thread synchronization to restrict concurrent access to shared resources. Thread synchronization constructs appear in varied forms. The three most common ones are semaphore, mutex, and critical section.
