Unless I'm misunderstanding this issue, no official glibc release was
ever affected which makes the probability of other people being affected
pretty small.
And this issue is about backwards compatibility only insofar, that it
works around a bug in some ancient cvs versions of glibc.
Is it a new policy that the kernel mustn't break any buggy userspace
code?
