Why would you want to instantiate the base class?

What's wrong with:

class Thread
{
    private:
        virtual void thread_func() = 0;
        static void start_thread(void* param)
        {
             static_cast<Thread*>(param)->thread_func();
        }
        void start()
        {
           os_specific_thread_starter(&start_thread, this);
        }
     protected:
        Thread() { }
        virtual ~Thread() { }
     private:
        Thread(const Thread&);
        Thread& operator=(const Thread&);
};

Then you have the following:

class MyThread : public Thread
{
     private:
       int n;
     public:
        MyThread(int n_) : Thread(), n(n_) { }
        ~MyThread();
     private:
       void thread_func()
       {
          std::cout << "Hello from thread " << n << std::endl;
       }
};

All you need to do is define thread_func.
