sl@0: // - Test and verify the results of the RRef assignment methods.
sl@0: // - Test and verify the results of the RRef smart pointer methods.
sl@0: // - Attempt to allocate all available heap space, verify that it 
sl@0: // cause a leave.
sl@0: // - Test and verify the results of the RRef allocation methods.
