When called for the first time, the current method creates a WaitHandle object and returns it. On subsequent calls, CreateWaitHandle returns a reference to a new wait handle.
Use this method if you implement the asynchronous methods and require a way of blocking in EndRead or EndWrite until the asynchronous operation is complete.
