I don't expect the review to take very long, but this is how it goes with releases. At some point, the release is cut, some bugs don't get fixed, and you will simply have to live with them. In any case, it entirely depends on how many ports it affects. I have the impression it is just a few particular ports having this issue? -Dimitry --Apple-Mail=_DE65C05B-4598-447D-A276-C96632AC7B52 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.22 (Darwin) iEYEARECAAYFAlQhcB4ACgkQsF6jCi4glqOiwgCg82MucrJ2w4sSohXqrG7Yb6jT VwQAn1ueoLb/j54vQEjbTMyhV/d3AqS7 =9Jdh -----END PGP SIGNATURE----- --Apple-Mail=_DE65C05B-4598-447D-A276-C96632AC7B52--
