HI Maxim Orlov Heikki Linnakangas
    Thank you for working on it,A few more days is a code freeze.It seems
like things have been quiet for a while, but I believe implementing xid64
is absolutely necessary. For instance, there=E2=80=99s often concern about
performance jitter caused by frequent freezes. If xid64 is implemented, the
freeze  process can be smoother.



Thanks
