The positional I/O code only landed with 335ccb, which is on master and 1.6,
but not on 1.4, which is why we haven't seen this problem before. I suspect
that the correct solution is both to take Ryan's pa

This fails on both Irix and AIX, as they don't have preadv64 and pwritev64. I don't
have either of those platforms in front of me, so it's not clear whether the

Actually, we're already carrying this logic to provide 64bit variants of all of
the other file manipulation functions we use. It's just that
