I think POSIX considering these functions as obsolescent is because it's
hard to define them in a way that's as portable as POSIX APIs try to be,
not because POSIX provides a suitable replacement for the application uses
of these APIs - much as with some other functions such as vfork. That is,
we should keep them as supported for applications trying to do less
portable things using them, because the scope of applications supported by
glibc is wider than that of portable applications supported by POSIX.
