I had anounced that I was working on some patch that fixes this problem and after that, I heared of this problem being currently worked on by several people. Douglas Gilbert mailed be about his current work on the problem. I have immediately frozen my work and said him that I left him complete his work.
People that work on this problem must be aware that linux-2.2 need this problem to be fixed and that only a clear, short and understandable patch has chance to be accepted by Linus. So, it is advisable to provide fixes as needed but not more, in my opinion.
Gérard.
