It's not going to solve anything at all. We can't stop supporting
functionality that has been there forever.
Well, the question is if you can keep the seekdir/telldir cookie around as a pointer -- preferrably in userspace, of course. You would presumably garbage-collect them on closedir() -- there is no other point at which you could.
I personally suspect that hch is right -- this stuff has been there since time immemorial and it'll be hard or impossible to deprecate it.
