    1.26 +Utility class for waiting for asychronous requests.
    1.27 +
    1.28 +This class allows asynchronous requests to be made from synchronous
    1.29 +objects. This object is used by passing its iStatus to an asynchronous
    1.30 +request and then calling Start(). The result of the request can be 
    1.31 +obtained by calling the Result() method.
