I'm (still?) not convinced this is a problem. Given O_EXCL, stat() and
fstat(), and sticky directories, I can't see what the danger is.
I discount admins doing things like leaving /usr world-writeable, or
/tmp non-sticky. I consider that akin to leaving /dev/mem mode 666:
you can do it, but you have nobody to blame but yourself. And it most
certainly is not for the system to protect you from the consequences.
