//  CBadApplicationDispatcher::CBadApplicationDispatcher
//
//  Arguments:  hClientProcess  =   HANDLE to the client process.
//
//  Returns:    <none>
//
//  Purpose:    Constructor for the CBadApplicationDispatcher class. This
//              stores the client handle. It does not duplicate it.

//
//  Arguments:  portMessage     =   PORT_MESSAGE request to queue to handler.

//              knows what kind of CAPIRequest to create so that
//              CAPIRequest::Execute will work correctly.

//              listen thread.
