    1.39 +An generic active object that can be used to wait for an iStatus to be signalled.
    1.40 +This has a similar effect to User::WaitForRequest(), but works without
    1.41 +blocking the thread (which allows other active objects within the thread
    1.42 +to continue).  Instead, a nested active scheduler loop is used.
    1.43 +
    1.44 +To use a CActiveWaiter, pass its iStatus to an asynchronous method, as usual.
    1.45 +Then call WaitActiveL() instead of SetActive().
    1.46 +
    1.47 +The call will block until the asynchronous completes.
    1.48 +
    1.49 +E.g.
    1.50 +
    1.51 +void CMyClass::Foo()
    1.52 +{
    1.53 +	CActiveWaiter* waiter = new(ELeave)CActiveWaiter;
    1.54 +
    1.55 +	iAsyncObj->Bar(waiter->iStatus);
    1.56 +	waiter->WaitActiveL();
    1.57 +	
    1.58 +	delete waiter;
