Yeah, cause the stuff was simply untested. There were/are no unit tests to
verify that the wrapper functions work as expected. Only nss_wrapper has a

What is this about now? So I should stop to get 'make test' working with the

What do you want, that I stop working on this? Why do we dance around the
