I have not forgotten, it is in TODO list. :)

I want to also inquire with Patrick about whether he is going to
perform the audit in this area which he said he wanted to do :-)

Well, we have patch which fixes the problem for the tester, so we

are other instances of the same return value propagation problem and
Patrick's audit is sure to turn up other similar turds...
