(no html, please).

   Proc does not need to be fixed, because /proc is referring to a file

Well, that does not mean /proc does not need fixing.

   You are expecting transactional behavior in /proc, where /proc only
   registers object information.
   And I think you would agree about your mis-interpretation earlier
   if not so
   many people had the same mis-interpretation of the virtual /proc

I think you understand the issue by now. But you think it should be
documented better, not fixed. I believe that fixing it is easier and
better option -- because surprises in security area are bad -- but of
course, if this is documented properly, it also stops being so big
