    This came up on the list quite recently. The source for the FreeBSD
    resolver.5 man page (/usr/src/share/man/man5/resolver.5) is maintained
    separately from the equivalent BIND source contributed from the ISC
    (/usr/src/contrib/bind/doc/man/resolver.5) The 'timeout:' and
    'attempts:' entries in the FreeBSD man page are there in HEAD and have
    been for 5 months, but (despite the CVS comment on version 1.10 of the
    page) haven't been MFC'd to RELENG_4 or RELENG_5_2 yet.

    Whether this means that support is available in the underlying
    resolver libraries is another question.

            Cheers,

            Matthew
