multithreading

Friends I have the following class that
class Singleton

{

private:

static Singleton *p_inst;
Singleton();

public:

    static Singleton * instance()
{

    if (!p_inst)
    {
        p_inst = new Singleton();
    }
    return p_inst;
}

};

Please do elaborate on precautions taken while implementing Singleton in multi-threaded environment ..

Many thanks
